Historical Overview

Founded in 1521 as the first permanent Spanish settlement in Puerto Rico, San Juan became the island's political, ecclesiastical, and cultural capital under the colonial crown. The Catedral de San Juan Bautista, dedicated to the patron saint John the Baptist, preserves the oldest sacramental records in Puerto Rico: baptisms from 1625, marriages from 1653, and burials from 1747, with older materials held at the Archivo Arzobispal in Old San Juan. As the original colonial center, San Juan's vast early jurisdiction gave rise to numerous later municipalities including Bayamón, Caguas, Guaynabo, Loíza, Toa Alta, Toa Baja, and Trujillo Alto. The municipality expanded in 1951 when Río Piedras was incorporated, adding its barrios and civil registration records to the San Juan research scope.

Coat of Arms

The coat of arms, granted in 1523, features a silver background with a green hill bearing the Agnus Dei (Lamb of God), the symbol of the patron saint San Juan Bautista (St. John the Baptist). The lamb holds a white pennant bearing a red cross. A gold border surrounds the shield, and a five-towered mural crown tops it, signifying city status. The Agnus Dei device is one of the oldest municipal heraldic symbols in the Americas.
