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 Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
