Izabal Lake

Lake Izabal, known in colonial accounts as the Golfo Dulce, formed part of the water route between Guatemala's interior and the Caribbean. The Río Dulce carried traffic from the lake toward the sea, while the Polochic connected its western side with the Verapaz country. Warehouses on this route held goods moving through a corridor that combined lake navigation, river travel and inland transport.

The same access exposed the warehouses and settlements to seaborne raiders. Spanish authorities developed fortifications at the lake's outlet during the seventeenth century; the stronghold became known as San Felipe de Lara. Repeated attacks in the later seventeenth century struck both the defences and the commercial installations. Raids in the 1680s extended into the Polochic route, showing that danger reached beyond the coastal entrance. Fortification remained an official concern in the eighteenth century. Engineer Luis Díez Navarro inspected the area in 1743, and Matías de Gálvez reinforced its defences in 1779. The lake consequently occupied a guarded passage between inland production and Caribbean shipping.
