Medieval defences unearthed at Edinburgh Castle

MEDIEVAL defences hidden from view for 250 years have been unearthed by archaeologists at Edinburgh Castle, it was revealed today.

Part of the city's historic boundary wall and the foundations of a defensive structure were discovered underneath the castle esplanade.

Experts believe the "extremely valuable" find will further their understanding of how the world-famous landmark evolved over the centuries.

The ancient defences, which date from at least the mid-16th century, were uncovered during foundation work to erect new stands for the Edinburgh Military Tattoo.

Archaeologists initially discovered the remains of a two-feet wide wall, which they believe to be part of the north perimeter boundary wall between the city and the castle.

Further digging unearthed remains similar to the foundations of a spur, a 16th-century structure which protected the entrance to the castle.

Both appear in a 1647 drawing by Gordon of Rothiemay but their exact location was not known until now.

The esplanade was formed in 1753 to create a military parade ground. As part of the process, a large amount of levelling was deposited on the area in front of the castle, covering up earlier buildings.

Peter Yeoman, head of archaeology at Historic Scotland said: "As the remains have effectively lain covered for over 250 years, this is a unique opportunity to learn more about the esplanade during this period in the castle's history.

"Until recently we have only had early drawings to go by but we are now able to examine the archaeology and record and preserve as much of it as is possible for future generations.

"The remains are too deep down to be displayed but to have this knowledge is a great step forward."

Archaeologists will now work with Tattoo bosses and contractors to record the remains before they are buried once more.

Culture Minister Fiona Hyslop, said: "Edinburgh Castle has a long and important role at the centre of the country's history.

"Finds of this kind are extremely valuable in terms of improving our understanding of the development of the castle, and its defensive needs during key periods in time."
