Fort de Bertheaume

Plougonvelin, France

The Bertheaume fort is a small part of the large coherent system of small forts and batteries designed to protect the entrance to Brest harbour. It is situated on a small island just 100m off the coast of the town of Plougonvelin. It was only accessible at low tide by foot over a rocky bank, attackers had to climb the steep cliffs first to reach the walls of the fort, an impossible job.

The medieval fort that used to be situated on the island was destroyed during an English attack in the 16th century. On his inspections of the Brest region in 1683 the famous architect Sebastien Vauban had already noticed the strategic value of the island and wanted to build a battery there.

The first cannon were placed there during the English attack in 1694 and the fort was finished in 1699. The original fortifications where situated only on the large island. The buildings on the smaller island closest to the mainland date from the 19th century. The fort on the large island consists of batteries for cannon on 4 levels connected with stairs. At some places the bases of the chauguettes can still be seen on the walls and posterns gave access to the foot of the walls.

In the past the island was only accessible by a boat at high tide. This was a small boat connected to a rope running from the mainland to the island. By pulling the rope the boat went to or from the island. The current steel bridge dates from the 20th century. In the late 19th century the fort was abandoned and was replaced by the more modern casemated fort on the mainland. The Nazis built a small blockhouse on the island.

In the 1990s the Fort de Betheaume was restored and opened to the public. Apart from the visit of the fort it also offers a survival track (only available when the weather conditions allow it). The fort is open to the public all year round. A small restaurant and various exhibition rooms are located in the 19th century fort. There you can also visit the underground powder magazine, carved in the rocks 13m below ground level.

Total waste of our time. Although the Fort was covered in "Adventures" all the gates were locked. There appears to be no way you can access this French Historic Monument as a tourist. Shame on you France.

Ancient fort with great History and magnificent views of the sea and the Goulet de Brest. The zipwire adventure looks amazing!

Easter Aquhorthies Stone Circle

Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.

The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
