Marsaxlokk is a beautiful fishing village in the south-east of Malta, famous for its Sunday market by the bay where you can buy all sorts of fish.
On the outskirts of Marsaxlokk, there’s a large watchtower and fort called Fort San Lucian dating back to 1610–1611. It has a long history, but it all started with a legend of a local woman who foretold an imminent Ottoman attack through a dream. Grand Master Alof de Wignacourt did not heed her warning, but that summer an attack did happen, and he subsequently ordered the building of the watchtower.
Today, the fort is home to the Malta Aquaculture Research Centre — a research facility for hatching marine species for mariculture.
The cache is located by the fort near a coastal path, which you can take for a lovely walk all the way to the heart of Marsaxlokk. Looking towards the freeport in Birżebbuġa, you can see some of the circular fish farming sites.
