La Perla is a historical shanty town astride the northern historic city wall of Old San Juan, Puerto Rico, stretching about 650 yards (600 m) along the rocky Atlantic coast immediately east of the Santa Maria Magdalena de Pazzis Cemetery and down the slope from (north of) Calle Norzagaray. La Perla was established in the 18th century. Initially, the area was the site of a slaughterhouse because the law required the homes of former slaves and homeless non-white servants – as well as cemeteries – to be established away from the main community center; in this case, outside the city walls. Sometime after, some of the farmers and workers started living around the slaughterhouse and shortly established their houses there.

The Center for Advanced Studies on Puerto Rico and the Caribbean (Spanish: Centro de Estudios Avanzados de Puerto Rico y El Caribe) is a private institute housed in the former San Ildefonso Conciliar Seminary in Old San Juan, San Juan, Puerto Rico that offers graduate studies in arts and philosophy.

However, it remained inactive and without organization until 1976, when Ricardo Alegría made a request before the Council on Higher Education of Puerto Rico to transform the center into an academic institution. The center is currently accredited by the Middle States Association of Colleges and Schools and it publishes La Revista del Centro de Estudios Avanzados de Puerto Rico y el Caribe.

The Catedral Basílica Metropolitana de San Juan Bautista, or in English, Metropolitan Cathedral Basilica of Saint John the Baptist, is the Roman Catholic cathedral of the Archdiocese of San Juan de Puerto Rico. The cathedral is one of the oldest buildings in San Juan, located in Old San Juan, the oldest cathedral in the United States, and is the second oldest cathedral in the Americas. Even though the Cathedral of Santa María la Menor in Santo Domingo in the Dominican Republic, is an older church building, the Cathedral of San Juan Bautista was the first cathedral church in the Americas as San Juan, then known as the city of Puerto Rico, was the first diocese of the New World with bishop Don Alonso Manso in 1511. The site is the location of the first church built in the New World. A private Puerto Rican foundation known as Fundación Protectora de la Catedral Metropolitana de San Juan, Inc. has been established to fund the historical restoration of the building and its art treasures for its 500th anniversary in 2021, and to protect it for coming centuries.

Edificio Patio Español (Spanish for 'building of the Spanish courtyard'), also known as La Filarmónica Building, is a mixed-use building located in the Old San Juan historic district of the city of San Juan, Puerto Rico. It was designed in a Spanish Mission Revival-style by civil engineer Eduardo Fossas López and built in 1937 with the purpose of refilling an emptied lot of the old city with a structure that resembled and referenced the Spanish Colonial architecture around it. This emptied lot was formerly the site of a meeting house for a group called Sociedad La Filarmónica ('Society of the Philharmonic'), a scholarly club that was founded by Manuel de Elzaburú and Alejandro Tapia y Rivera with the intention of promoting cultural activities in the city of San Juan. The Patio Español building was added to the National Register of Historic Places in 2005.

Plaza de la Catedral (Spanish for 'cathedral square'), also known as Plazuela de las Monjas ('little square of the nuns'), is a small public square located in front of the Cathedral of San Juan Bautista and next to the former Carmelite convent (now a Hotel El Convento) in the Old San Juan historic district of the city of San Juan, Puerto Rico. The small but historic square is possibly the oldest in the city, dating to the foundation of the cathedral in 1521, and is found at the end of a wide historical residential block bound by the alleyways (Spanish: caletas) of Las Monjas and San Juan to the north and south, respectively, and by Calle del Cristo ('del Cristo Street') to the east. Caleta de San Juan connects this square to the San Juan Gate (Puerta de San Juan), formerly known as the Water Gate (Puerta de Agua) as it was the main harbor entrance into the walled city. This block formerly contained the first Episcopal church in the city between 1909 and 1929 when it was moved to a bigger location in Santurce, and later housed the San Juan Children's Museum (Museo del Niño de San Juan), which closed in 2016.
