Overview

Forum Complutum represents the public and administrative heart of the ancient Roman city of Complutum, located in modern-day Alcalá de Henares. The site features the remains of a monumental central square surrounded by porticoes, administrative buildings, and a basilica. Excavations have revealed sophisticated urban planning, including drainage systems and mosaic floors preserved in situ. As the capital of the Roman district, it served as a primary hub for judicial, commercial, and religious activities. The archaeological park provides visual evidence of the transition from late Republic to late Imperial Roman urban design. Visitors can observe the layout of the curia, where the city council met, alongside various tabernae or shops.

Insider tips

Wear sturdy, closed-toe walking shoes as the terrain consists of uneven stone and gravel paths.

Bring a hat and high-SPF sunscreen as the site has minimal natural shade and high sun exposure.

Download a digital map or guide beforehand, as on-site signage is primarily geared toward academic interpretation.

What to avoid
