Responsibility for construction has changed several times since the introduction of the Ministerial Constitution in Prussia in 1808. Since 1808 building matters were dealt with in the 2nd Section for Trade Police in the Ministry of the Interior, in 1814 they were transferred to the Ministry of Finance. In 1817 an independent Ministry for Trade, Commerce and Construction was formed from the corresponding section, which was dissolved again in 1825. After the dissolution of this ministry, the building cases were successively assigned to different ministries and were returned to the Ministry of Finance in 1837, where they remained until the creation of the Ministry of Public Works in 1878. The newly created Ministry was also responsible for railways (see: I. HA Rep. 93 E). As the central authority for building construction, railways, roads and hydraulic engineering, the Ministry and its subordinate authorities and bodies were responsible for planning, designing and supervising the execution of the works carried out by the State in these areas. The Ministry cooperated with the military building authorities in the construction of military buildings. When the Ministry of Public Works was dissolved in 1921, the railway administration and part of the hydraulic and road works were transferred to the Reich. The rest of the portfolio was divided among the Prussian Ministries of Trade and Industry, Agriculture, Domains and Forests, and Finance. The building construction was transferred to the Ministry of Finance and formed its own department there. Heinrich Waldmann has conducted a detailed investigation into the history of the ministry (including the previous authorities). Annex V of the paper also contains an overview of the periodicals published by the Ministry. The indexing and organization of the building department of the Ministry of Public Works was carried out in 1968 by the archivist Maria Lehmann under the guidance of the lecturer Heinrich Waldmann. At the same time, the files that had accumulated at other ministries before the creation of the Ministry of Public Works were brought together in this inventory. This also applies to files of the building construction department of the Ministry of Finance, in so far as they were proven to be assigned to the Ministry of Public Works. The stock Ministry of Public Works is divided into four departments: 1 Administration 2 Building construction 3 Road and bridge construction 4 Hydraulic engineering In the years 1995/96, the part of the stock remaining in Dahlem Ministry of Public Works (208 VE) was dissolved and for the most part included in the stock I. HA Rep. 93 B Ministry of Public Works incorporated. 61 file volumes were assigned to the Railway Department (I. HA Rep. 93 E). The production of a finding aid book was all the more necessary, since so far as finding aids only the finding aid card index provided in the year 1968, meanwhile badly readable, partly damaged and not yet finally edited was present. Some title recordings were checked for questionable spelling of individual place and person names or questionable dating on the basis of the tape in the outdoor magazine. In the stock Rep. 93 B the former stock Rep. 93 C was already incorporated in Merseburg. In the literature a part of the files of the Ministry of Public Works are still cited with the inventory designation Rep. 93 C and old file number. A corresponding concordance was therefore compiled in a separate volume. In 1992, 12 linear metres (405 units) of files from the Prussian Ministry of Public Works were transferred from the Bundesarchiv Potsdam to the Geheime Staatsarchiv PK. In November 1990, the files had been transferred to the Federal Archives under the provenance of the Reich Ministry from the Military Interim Archive Potsdam, into which they had entered in 1971 from the Administrative Archive of the National People's Army. These files, which have been valid since the Second World War for lost files, concern lighthouse and nautical marker matters on the Prussian coasts of the Baltic and North Seas in the period from 1800 to 1932. A large number of the volumes contain maps, site plans, technical drawings with scale specifications, construction sketches as well as blueprints of lighthouses and lighthouse parts or other inventions in nautical marker matters. About 100 files form the file group "Handakten des Seezeichenausschusses" . Most of these files were recorded by Dr Meyer-Gebel, Dr Strecke and the undersigned in the period 1992 to 1993. The incorporation of these archival documents and the technical processing of the magazine into the hydraulic engineering department took place in 1996. Furthermore, from the end of 1996 to 1998, 110 packages (905 units; approx. 15 linear metres) with the designation "Rep. 93 unprocessed access Magdeburg" were recorded, which were stored at the end of the inventory. The origin of the name "Zugang Magdeburg" is not comprehensible. In the inventory file "Economy and Transport" from the period from 1959 to 1974 no such information could be found. In contrast, in the file "Aktenzugänge, 1965-1974" (Access to Files, 1965-1974), it was possible to ascertain a case of a larger file transfer from the German Central Archive Potsdam in 1970. The archives mainly consist of hydraulic engineering documents, including river regulations, harbour, dune, bank and lock constructions, as well as memorandums, calculations, maps and plans (some coloured) on the construction and extension of waterways. These include 29 volumes from the Planning Chamber of the Ministry of Public Works, including an inventory extract of the maps and town plans available in the Planning Chamber. Oversized maps or plans as well as drawings were taken from the holdings and assigned to the XI HA General Map Collection. 211 file volumes, mainly journals and index volumes, have been incorporated into the Railway Department (I. HA Rep. 93 E) of the Ministry of Public Works inventory. When the files were entered into the Oracle database of the Secret State Archives, the data records of the holdings already entered under the old IT system were corrected or standardised. In February 1999 the magazine-technical processing took place. The Department of Hydraulic Engineering is now the most comprehensive collection of the Rep. 93 B Ministry of Public Works. Due to the frequent change of responsibility for the building industry, the holdings of the I. Main Department Rep. 77 Ministry of the Interior, Rep. 87 Ministry of Agriculture, Domains and Forests, Rep. 120 Ministry of Trade and Industry and Rep. 151 Ministry of Finance are to be consulted in addition to the holdings listed below. As part of the preparation of an inventory of the Prussian building administration until 1848, files from the Ministry of Public Works, among other things, were made accessible in detail.

The present collection contains maps and plans of the Langenburg archives of various kinds. On the one hand, there are forest maps, which are often found in the tradition of the nobility. Their purpose is to show the location of the noble territories: often they are printed maps such as cadastral maps in which the boundaries are drawn by hand. There are also maps on the forest use of the forest with information on the trees planted and the yield; a hunting map is also included. Another group are the war maps, a collection of different maps of the wars from 1870/71 to the First World War inclusive. The origin of the collection is not known, except that it comes from langenburg provenances. The plans are plans of the existing castle in Langenburg (i.e. not building plans) from the 1950s from the different points of the compass, which were prepared by a doctoral student for art historical research purposes. The processing of the inventory took place in two phases: The forest maps (57 pieces) were catalogued around the year 2000 by the employee Dirk Niklaus as part of the processing of the printed maps (mainly stock GA 105). After other map groups appeared - the war maps and the plans - and their provenance context became clear, Günther Coels also worked on these groups in the summer of 2010 and also transferred the title recordings of the forest maps to the Scope database. Mrs. Diane Leutwein created the index. The final processing of the collection was carried out by the undersigned and took place in spring 2011. The collection comprises 202 maps from the period 1828 to 1959.Neuenstein, July 2011Dr. Schiffer

Foreword: This section currently contains about 7,500 registered maps, nautical charts and site plans. In line with the DTM's interest, the focus is on traffic maps. One of the oldest maps in the collection is a collection of very decorative nautical charts, mostly from Europe. They date from the 17th and 18th centuries. The collection of the Museum für Meereskunde includes a number of nautical charts from the period 1860 to about 1920. Finally, there are a number of more modern nautical charts, mainly from the German coasts, which were handed over to us by the Förderverein. So there are many examples for the development of the nautical chart. The early postcards and travel cards were used for traffic on land. This genus is represented by some cards from around 1800. With the increase of private journeys with the development of the railway, the demand for maps for the German and European area also grew. This can be clearly seen from the various railway and travel maps of Central Europe which were published by numerous publishers from the 1940s onwards. The rapid growth of the railway network can be easily tracked on the maps. These maps also clearly show stagecoach connections next to the railway lines until after 1900. The geographical focus of the map collection is on Berlin - Brandenburg - Germany - Central Europe. Thus the German area is well covered with the railway maps. From the "Metzeltin" (railway historian) collection, however, many maps on the subject of railways from overseas have also been added to the DTM collection. In the last half of the last century, another popular type of traffic map appeared: the road map. In the beginning still under the name "Cyclist Card". Later they are called "cyclist and motorist maps" and finally only "car maps". Until the 1930s, many leading petrol distributors, tyre manufacturers and some well-known publishers in Germany had card series for the German-speaking countries in their product range. Examples of map series publishers are Aral/BV, Olex/BP, Standard/Esso, Stellin/Shell, Continental, Ravenstein and Ullstein/BZ. This area is well represented in the DTM portfolio. Examples of almost all series are available, some series are almost complete in single sheets, but rarely available in all editions. With the increase in leisure time and mobility from the beginning of this century, more and more hiking maps appeared. They are increasingly available in the DTM map collection for holiday areas such as Schneekoppe and Harz, but also for trips to the Mark Brandenburg. Particularly numerous Silva and Pharus hiking maps have been preserved. The very exact maps of the Reichsamt für Landesaufnahme in Berlin were very popular for the closer surroundings of Berlin. The series "Karte von Berlin und Umgebung in 12 Blätter" on a scale of 1:50,000 was published from 1901 to about 1943 in several new editions. In the 1930s, a series of maps for water hikers was published covering the Brandenburg and Mecklenburg lakes and waters. Today, this type of map becomes up-to-date again and the older maps are used for information purposes. The urban developments in the Berlin area can also be clearly seen in the city maps. For the period after 1870, plans of Berlin are available at short intervals. The development of local public transport can also always be seen on city maps. However, it can be more directly traced on the maps of the Public Transport Classification Group. A large number of maps from Berlin are also available here. Among the early maps are the Droschken path knives from the period 1880 to 1920. Some maps of the Berliner Straßenbahn Betriebs GmbH and the Hochbahngesellschaft are also available. However, the focus is on the BVG line networks, which have been represented in large numbers in the portfolio since 1930. A collection of about 10,000 nautical charts from the former Institute of Geography, which was taken over by the TU Berlin, is stored and accessible according to the publisher's system. The training in this database takes place as required.
