The Fortaleza de San Fernando (also known as the Castillo de San Fernando de Omoa) is a colonial-era Spanish fortress in Omoa, Honduras. Built between 1756 and 1775, the fortress guarded Spanish interests in the-then Captaincy General of Guatemala before being seized by the Honduran government in 1821. The fortress remains relatively intact, and is a major tourist attraction in Omoa. Read more on Wikipedia
