Hello,  one more from Gibraltar.  This from the 1953 issue. Another very nice issue with some very well presented  images.

Some history and trivia you might find interesting - Rosia Bay is the only natural harbour in  Gibraltar. 

It was formerly referred to as Rosia Harbour, it is located on the southwest side of Gibraltar. 

Rosia Bay was the site of the Royal Navy Victualling Yard complex which was constructed in the early 19th century, allowing vessels to anchor and obtain provisions, including food and water. Vice Admiral Horatio Nelson obtained supplies for his Mediterranean Fleet at Rosia Bay. It was to that same anchorage that his vessel HMS Victory was towed after Nelson's death in the 1805 Battle of Trafalgar.
