A cave that doubles as a concert venue?

..Just a few more photos of some interesting sights to see in Gibraltar.

The first couple are of Moorish Castle which has to be one of the oldest castles I have ever visited dating back to the 8th century! Since its construction it has had many interesting uses and has with stood many invasions the small country has battled with through the ages!

The last one is of the inside of St Michael's Cave which was so beautiful to visit. The Gibraltarians actually use the cave to host concerts which is a bit worrying seen as they have these huge stalactites hanging from the ceiling!
