Kolumba Art Museum that located in Cologne, Germany, the new building designed by Peter Zumthor transfers the sum of the existing fragments into one complete building. In adopting the original plans and building on the ruins, the new building becomes part of the architectural continuum. The warm grey brick of the massive building unite with the tuffs, basalt and bricks of the ruins. The new building develops seamlessly from the old remains whilst respecting it in every detail. In terms of urban planning, it restores the lost core of one of the once most beautiful parts of Cologne’s city centre. Inside the building a peaceful courtyard takes the place of a lost medieval cemetery. The largest room of the building encompasses the two thousand year structure of the city as an uncensored memory landscape.
