A small limestone shelter set in the cliffs above the coast at L-Aħrax, the Latnija cave is one of the most important recent archaeological sites in Malta. Excavations through the early 2020s revealed evidence of mesolithic hunter-gatherers, predating the temple-building cultures by roughly a thousand years and rewriting the textbook story of how the islands were first peopled.
The site itself is fenced and not generally open to the public — work is ongoing — but the cliff walk above it from the Red Tower is a fine outing in its own right and an interpretation board sets out the find. Check with the Mellieha tourist office for any visitor days announced for the dig season.
