The district is compact, with narrow streets, plazas, and open spaces integrated into the urban fabric. Surrounding areas include parks, local residences, and riverside promenades.

Architecture and Urban Layout
The district's buildings feature colonial-era stone and adobe construction, with tiled roofs and wooden doors. Streets are irregular and follow the contours of the original settlement, creating a distinctive historic urban layout. Key landmarks include the lighthouse, city gate, and historic churches.
