It’s Fort Amsterdam in Sint Maarten.
The fort was given its name 270 years ago. Its walls and sentry houses show the unique process used to build ancient architecture. Fort Amsterdam was used as a guardian of the Great Bay, the builders failed to consider the fact that cannons and guns cannot adequately span and guard the 1,600 meter-wide bay. The criss-crossed path leading to Fort Amsterdam is currently one of the best hiking trails in Sint Maarten.
