Chur- Obertor (Gate Tower)

Together with the Maltese tower and the Sennhof tower, the Obertor is one of the surviving towers of the mediaeval town fortifications. With its impressive appearance, the Obertor soon became a symbol of Chur. The four-storey tower, tapering towards the top, blends in with the structure of the housing development which is based on the town walls, but at the same time, with its ligher stonework, it stands out from the terraced row.
