A compact but delightful display of shiny brass gears, rods and chains that claims to tell the time for the next 10,000 years or more. The surrounding material describing the design, construction and maintenance is worth a gander.

This is an impressive 'little' exhibition in Copenhagen's town hall. The clock is a massive (for a clock at least), shiny and intricate mechanical marvel of clockfaces, cogs and gears that Jens Olsen assembled over many years. It was finished in 1955, ten years after...More

My husband has an interest in time and space. We were thrilled to find this small and unusual ( and free!) exhibit. Quite fascinating even for the uninitiated.
