More Old San Juan Landmarks Not to Miss:
Seminario Conciliar de San Ildefonso
The original building was completed in 1832 and it was commissioned by the first Puerto Rican Bishop, Fray Juan Alejo de Arizmendi. The seminar became a cornerstone in the development of public education in Puerto Rico, under the long teaching tradition of the Catholic Church. The Dome at the Chapel is a work of art worthy of a visit.
Department of Treasury Annex
Located in the main square Plaza de Armas, it served as the depository of the royal treasure on the Island. It was also the first headquarters of the provincial deputation that preceded the modern-days legislative branches.
