Project details : The filigree glass extension housing administrative offices, library and multi-purpose areas is situated on the outer area of the Cyriaksburg defence walls. All that can be seen of the new building by visitors approaching through the grounds of the Erfurt Horticultural Exhibition is the anthracite grey outline of the post and beam structure that covers the plant-filled atrium and extends 3 m over the edge of the moat. The dominant feature is still the roof and eaves of the Cyriaksburg. The new building reveals its unassuming presence to visitors stepping through the main entrance of the museum in the moat area. The glass facade mirrors the heavy stones of the former fortress and seems at the same time to dissolve them. This sequence can also be read as a progression from the enclosed stone walls to the light-filled intermediary world of the new building and culminating in the open space of the garden.
