Unique in Greece, the Rotunda is a cylindrical building from the early 4th century AD. The mosaics inside are really impressive. The Rotunda is a massive circular structure, built in 306 AD, with a masonry core. Through its long history, it has gone through multiple periods of use and modification as a polytheist temple, a Christian basilica, a Muslim mosque, and a Christian church once again. A minaret is preserved from its use as a mosque, and ancient remains are exposed on its southern side. Some Greek publications claim it is the oldest Christian church in the world. These days, the Rotunda is primarily an archaeological site, where you can see some remaining Christian mosaics and feel the weight of history.

Australia's got Ayer's Rock, Ireland — the Blarney Stone, and Gran Canaria has Roque Nublo. The Cloud Rock seems a little bit of an odd name. Usually, you can see for miles and miles from this famous vantage point. Walk there from La Goleta parking lot, located on the Ayacata-Pozo de las Nieves road.
