The Palacio Árabe is one of the more unexpected sights in Mar del Plata's city centre — an ornate Neo-Mudéjar building with horseshoe arches, intricate tilework, and decorative minarets, sitting a block from the main shopping street. Built in the early 20th century for a wealthy immigrant family, it is now a cultural centre and events space.
The exterior is the main attraction: the combination of glazed tilework, carved stone, and Arabic-inspired geometric patterns makes it one of the most photographed buildings in the city. The interior, when events are not running, is usually open for a quick look. A good example of the immigrant-driven architectural eclecticism that characterises many Argentine city centres.
