. A number of notable buildings and structures have been built in and around the vicinity of Plaza Lacson. Aside from the Santa Cruz Church on its north side, the plaza's most famous landmark is the
Roman R. Santos Building, one of Manila's few surviving examples of pre-World War II
neoclassical architecture. The building, first built in 1894 and expanded in 1957, was the headquarters of
Prudential Bank until 2005, when it was acquired by
Bank of the Philippine Islands (BPI). BPI continues to maintain a branch on the building's ground floor. Previously, however, the building was the headquarters of the Monte de Piedad Savings Bank, the former banking institution of the
Catholic Church in the Philippines, from 1894 to 1937, and also served as an
American Red Cross-operated hospital from 1945 to 1947. Other Philippine financial institutions have had their headquarters around the plaza at some point in their history.
Security Bank was headquartered at the ground floor of the Roman R. Santos Building from its establishment in 1951 until 1954, when the building was still under the ownership of its prior owner, Consolidated Investments.
Philtrust Bank opened its headquarters at the plaza in 1950, located beside the Santa Cruz Church, and remained here until it relocated to its current headquarters along
United Nations Avenue. The building still houses the bank's Santa Cruz branch. Located beside the Philtrust Bank building was the
Ideal Theater, the first major building designed by
Pablo Antonio, said to be the Philippines' foremost
Modernist architect. Unfortunately, the building was demolished in the 1970s to make way for a shopping mall. There are also significant transport-related structures which are in the vicinity of the plaza. The Philippines' first
traffic light was installed in the plaza in 1938, and although Manila's tram network was dismantled after World War II, the
LRT Line 1 Carriedo station is located on the opposite end of the plaza, at the intersection of Carriedo Street and Rizal Avenue. ==See also==
