What it is

A medieval fortress with a stone keep built on the Ozama River to protect Santo Domingo, the first permanent European city in the Americas. It is the oldest surviving European military building on the continent.

The forts of Navidad (1492) and La Isabela (1493) are older but of wood or ruined; the keep was raised between 1503 and 1507 and the enclosure was extended later.

What it led to

  • a model for Spanish colonial fortifications in the Caribbean
  • defence of the monarchy's main port in the Indies in its early years
  • a first step towards American bastioned architecture
