The city has inherited a monumental architecture of the colonial and republican times features typical of the Andalusian architecture (southern Spain), with materials and techniques used by Native Americans based in the mud, like adobe and wattle, which gives it a unique personality. Equally characteristic has a certain pattern that combines traditional Spanish checkerboard layout with an irregular shape typical of medieval German cities, product of the period in which the city was the seat of the domain of Welser. In the central town, some streets end abruptly, breaking the regularity of the Spanish checkerboard. Ambrosius Alfinger (German of the house of the Welsers and first Governor of the Province of Venezuela) restructures the layout of the streets based on the original layout of the founding of the city.
