The main draw in terms of architecture in Puerto Vallarta is the  La Iglesia de Nuestra Senora de Guadalupe, located on Calle Hidalgo (one block from the main square), which was constructed over a 12 year period beginning in 1929.  It is a Baroque-style church with hand carved columns and detailed molding inside.  The church is topped by a crown modeled after that of Mexico's 19th century Empress Carlotta. La Iglesia de Nuestra Señora de Guadalupe is often mistakenly called a cathedral but it is simply a church as the Bishop of the Diocese does not hold the throne here.

Traditional architecture groups in Puerto Vallarta blend elements of mountain and coastal architecture in building homes.  Mountain architecture is a more internal, protective style, with small windows and internal courtyards, whereas coastal homes are more open due to the hotter coastal climate.  Additionally, foreigners have historically had a great impact on Puerto Vallarta architecture, with the Spanish importing the style of arches, domes, and courtyards that dominates the architecture of Puerto Vallarta.  You will also see colonial and adobe (often whitewashed) buildings and red-tile roofs.
