The new Museum Depot, City Archive and Youth Center are located on a slightly descending lot which was previously occupied by a car dealership, abandoned many years ago. This position at the foot of Castle Hill is particularly characterised by its direct adjacency to the historically listed building “Mainzer Tor”, which was constructed at the end of the 14th century as the western city gate to Miltenberg. In our design concept, the building site was levelled by a single-storey base structure in manually hewn red Main sandstone, which houses the museum depot and the city archive. From this massive base, two glassy building laterns, positioned diagonally over a corner, arise and accentuate the town entrance. In their light and at night backlit materiality of translucent profiled glass they form an aesthetic contrast to the stony base structure. The wide exterior staircase leads from Mainzer Strasse up to the roof surface of the depot which forms a small public plaza, framed by the two single-storey cast glass buildings. Entry to the youth center in the southern body takes place directly from here. From the plaza and via a new bridge, the adjacent “Mainzer Tor” can be accessed and be experienced as the entrée to the city.
