The Castle of la Punta de Amer is a 17th century fortification located in Sant Lorenzo des Cardessar on the island of Mallorca. The sandstone structure was built in the late 17th century, and is now a protected site.
During the 16th century, the need for guarded coastlines arose as pirates from northern Africa and the Ottoman empire continuously attacked Majorca.
However, the final decision of erecting this fortress was not made until a violent attack happened in 1611 which caused severe damage to the east cost. Due to financial struggles and economic decline in Manacor, the construction of the fortress began 1693 and was finished in 1696.
The fortress rises 35 meters above sea level. During service time, the fortress was guarded by 2-3 guards, armed with sables, muskets and pistols. Moreover, the tower was equipped with a canon on the platform which could shoot at hostile ships entering the bays of Cala Millor and Sa Coma. The original cannon is still here by the way.
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.
