The square is surrounded by elegant neocolonial and republican-style buildings, such as the Hotel Bolívar, the Teatro Colón, the Club Nacional, the former Cine Metro building, the Zela and Pumacahua portals, and the sculptural group known as “The Three Graces.”
At its center stands an imposing monument in honor of the liberator José de San Martín, created by the Spanish sculptor Mariano Benlliure. Together, these elements enhance the beauty and cultural importance of the site. The Historic Center of Lima was inscribed by UNESCO, first with a declaration linked to the Convent of San Francisco in 1988 and later with an extension to the Historic Center in 1991. Plaza San Martín is part of this monumental ensemble, but it was not declared individually.

The square was inaugurated on July 27, 1927, as part of the commemorations of the centennial of Peru’s independence. It was designed by the Spanish architect Manuel Piqueras Cotolí. The square features a neobaroque composition, visible in its layout, ornamentation, benches, balustrades, and sculptures. It is located on the site once occupied by the former Plazuela de San Juan de Dios.
It is located in the heart of downtown Lima, about 700 m southeast of the Plaza Mayor.
Every element of this square has a monumental character. It features colorful gardens, bronze lampposts, marble benches, granite paving, four water fountains at the corners, and, in the central area, the monument to Don José de San Martín. Among the major buildings surrounding the square are the Teatro Colón, the Giacoletti Building, the Hotel Bolívar, the Zela and Pumacahua portals, and the former Cine Metro, among other structures that make it one of the most beautiful squares in Lima.
It is a generally safe area and is regularly monitored by police officers and Lima’s municipal security staff. Even so, we recommend keeping an eye on children, taking care of personal belongings, and staying alert. If you visit during the day and plan to explore the Historic Center, wear a hat and long sleeves, as solar radiation can cause sunburn even on cloudy days. Sunscreen is also recommended. It is best to avoid walking through poorly trafficked areas.
Plaza San Martín is a public space with free access. It is recommended to visit during the day or as part of a guided tour through Lima’s Historic Center.
