Gibraltar's swashbuckling history unfolds in this fine museum, which comprises a labyrinth of rooms and exhibits ranging from prehistoric and Phoenician Gibraltar to the infamous Great Siege (1779–83). Don’t miss the well-preserved 14th-century Islamic baths, and a 7th-century-BCE Egyptian mummy found in the bay in the 1800s.
The museum also has displays on local bird life (past and present), along with Carthaginian artifacts recovered from the Rock's east-coast, Unesco-listed Gorham's Cave Complex, which it also runs trips to from July to October.
