The fort has a dark past: It once held political prisoners and was used by the National Guard to mortar-bomb the city during the 1980s revolution. It was also the location of the heroic last stand by national hero Benjamín Zeledón against U.S. Marines in 1912. Now, it is a quieter place, with helpful boy scouts conducting visits of the facility and its unwelcoming dungeons. Whitewashed battlements and squat, yellow-domed towers overlook the city and lakes, and afford a pleasant visit that belies this structure's dark history. The fort is a 1km (1/2-mile) hike north of the old train station, but I recommend taking a taxi (fare C20), as it is a fairly hard stroll.
