Mercado de las Carnes (English: Meat Market), also known as La Plaza de los Perros (English: Dogs' Plaza), but formally, Plaza Juan Ponce de León (Juan Ponce de León Plaza), was the first building in Puerto Rico to mix social and architectural elements via the pedestrian mall concept. The historic Art Deco architecture structure is located in Ponce, Puerto Rico, and dates from 1926. It was listed on the National Register of Historic Places in 1986. The Plaza was rebuilt in 1992, under the administration of Mayor Churumba. It is located in the alley connecting Mayor and Leon streets, in the block between Estrella and Guadalupe streets. The Plaza and the alley are one and the same.
