Monument preservation plan

Record of historic building fabric in Troisdorf

The monument preservation plan covers all the historic building fabric of Troisdorf. According to § 12 of the Monument Preservation Law (Denkmalschutzgesetz), cities and municipalities must draw up a monument conservation plan. This is a special plan that covers all matters of monument protection and conservation, including the conservation of urban heritage. The plan was drawn up in the form of a commissioned report, 50% of whose costs were funded by the state of North-Rhine Westphalia in order to protect and preserve the state's cultural heritage.

The aims of the monument preservation plan are an area-wide record of all the findings of importance to the protection of historical buildings and archaeological sites, a preliminary evaluation of building stock in need of preservation, and recommendations with regard to planning and courses of action.

Protection of streets and squares worthy of conservation

As well as the protection of individual historical buildings and archaeological sites, the Monument Preservation Law also provides an opportunity to list complete entities that do not consist only of historical buildings. The following are currently designated heritage sites in Troisdorf:

- the Black Colony (Schwarze Kolonie)
- the Red Colony (Rote Kolonie)
- the casino district.

The heritage sites are a testament to working and living conditions within the catchment area of the Mannstaedt Works in Friedrichs-Wilhelms-Hütte. The monument conservation plan recommends that other entities, including the market square in Sieglar and Elisabethstrasse, should be listed.

Notes on the preservation of building fabric

The monument protection plan also flags up groups of buildings and settlements worthy of conservation which may not meet the strict criteria for monument protection but do fulfil the requirements to qualify as a preservation area under § 172 of the Federal Building Code, due to their significance in terms of local character and building history. A preservation order may be issued under local planning laws in such cases. The plan also refers to individual properties and settlements that do not have the character of a monument but may nevertheless be significant contemporary witnesses of urban development.

Monument conservation plan presented to the public

The monument conservation plan was unveiled in public on 02.12.2010. This was preceded by a drafting process that took nearly two years and incorporated members of the public. In October and November 2009 the districts held public information events, at which all manner of questions on the draft monument conservation plan were answered by Prof. Werling from the assigned architectural practice Voigt-Werling and by the city of Troisdorf in its capacity as the Lower Authority for the Protection of Monuments (Untere Denkmalbehörde).

Basis for further plans

Troisdorf city council passed the monument conservation plan in its meeting held on 05.10.2010 as the basis for further plans and activities within the urban area. It must be pointed out here that the monument conservation plan was unable to carry out a thorough investigation into the suitability for preservation of the proposed historical buildings and heritage areas, which will necessitate a further specialist review. Other interests have not yet been taken into consideration in the case of buildings worthy of preservation; this must be done if recommendations for preservation are implemented by law.

The Culture Office became the Lower Authority (only in German available) for the Protection of Monuments on 01.06.2011; the Office for Urban Development and Geoinformation is responsible for drawing up preservation orders.
