Trujillo’s historic centre is not a sealed colonial set. It remains part of a working northern Peruvian city, where civic offices, churches, museums, homes and shops meet around the Plaza de Armas. The plaza is the best place to orient a first walk: its open centre gives way to streets lined with historic façades, while the cathedral and municipal buildings help explain how public authority and religious life shaped the urban core.
The Ministry of Foreign Trade and Tourism’s inventory describes the monumental area as approximately 133.5 hectares. That figure helps explain why the historic centre is more than a single square or a handful of landmark houses. Its streets preserve a broader urban setting, including blocks and public spaces where architecture from the viceregal and republican periods sits within contemporary daily life. The important distinction for visitors is between a compact route through highlights and the much larger protected area.
