The postcard supposedly shows the Provincial Capitol of Basilan; however, when I try to research it, the provincial capitol does not even look as what is shown in the postcard.
Basilan Provincial Capitol is former site of Fort Isabela Segunda, Isabela City, Basilan. The original Fort was bombed and destroyed towards the end of World War II, having been used by the occupying Japanese forces as a munitions dump. A newer capitol building was built on the spot where the old Basilan City Hall stood after it was burned in the early 1990s. The new building is a celebration of Muslim and Christian influences which shaped modern-day Basilan, and still occupies the highest point of the City proper.
Could the postcard show the old Basilan City Hall and not the provincial capitol?
