Almost all of Manila's prewar and Spanish colonial architecture were destroyed during its battle for liberation by the intensive bombardment of the United States Air Force during World War II. Reconstruction took place afterwards, replacing the destroyed historic Spanish-era buildings with modern ones, erasing much of the city's character. Some buildings destroyed by the war have been reconstructed, such as the Old Legislative Building (now the National Museum of Fine Arts), Ayuntamiento de Manila (now the Bureau of the Treasury) and the under construction San Ignacio Church and Convent (as the Museo de Intramuros). There are plans to rehabilitate and/or restore several neglected historic buildings and places such as Plaza Del Carmen, San Sebastian Church and the NCCA Metropolitan Theater. Spanish-era shops and houses in the districts of Binondo, Quiapo, and San Nicolas are also planned to be restored, as a part of a movement to restore the city to its prewar state.
