From a distance, the dome of the Zug clock tower appears blue-white but as you get closer to it, you can see the time on it. But not just the time, it also shows the month, the phase of the moon, the day of the week and whether it is a leap year or not. The tower was actually built as a way through the oldest city walls and later part of it was used as a prison as well as housing a room to keep warm by an open fire. Today the 52-metre-high tower is open to everyone, an opportunity not to be missed. After all, where else other than Zug can you get the key yourself to a city landmark.
The tower was originally built in the 13th century and heightened in 1478-1480. The current appearance dates from 1557.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
