La laguna fortificada de aooot raiti bocay, Spanish colonial fortress in El Castillo, Nicaragua.
The Fortress of the Immaculate Conception stands on the southern bank of the San Juan River with stone walls and watchtowers monitoring the waterway.
Spanish military engineer Martin de Andujar Cantos completed the fortress construction in 1675 to protect Granada from pirate attacks through the San Juan River.
The fortress museum exhibits military artifacts and documents that demonstrate the Spanish colonial influence on Nicaraguan defense infrastructure in the 17th century.
Visitors reach the fortress by taking a motorboat from San Carlos, with guided tours available in multiple languages throughout the operating hours.
British naval officer Horatio Nelson led a successful capture of this fortress in 1780, marking his first major military victory.
