What’s left of the original site of the city are the ruins of the fort Columbus ordered built and a church. After the great earthquake of 1562, most of what remained of the structures was taken to the latter-day La Vega, where it was used in construction. With some imagination and the help of a guide (Spanish speaking only), it’s possible to begin to grasp the historical implications of what you’re seeing.
A small museum in the back of the site contains both Taíno and Spanish tools, weapons and ceramics. The cost of admission and guide seems open to negotiation and depends on the number in your party.
To get here, continue around 4km past the turn-off for Santo Cerro and look for an old and battered sign on the left-hand side of the road.
