Postal bus station. The postal bus station is covered by a glass dome. At night, the structure is illuminated by spotlights, lighting up the centre of Chur. There is also a gently domed glass and steel structure over the platforms of Chur station. In its appearance, the 300 m long span of the unsupported glass roof is reminiscent of railway halls from the 19th century. Architects: Richard Brosi and Robert Obrist.
