With the pacification of the region in the 1st century, the Roman army withdrew from the city’s High District, an area spread over three terraced steps. The intermediate step contained the provincial forum, the political and administrative nerve centre of the province of Tarragona. Today, this once vast plaza with its surrounding arcade is home to dozens of houses and streets. There, visitors can see the remains of the portico in the buildings of the "Antiga Audiència", or the Old Court of Justice, (southwest tower), in Plaça del Pallol (entranceway, vault and pilasters of the Old Nunnery), in Plaça del Fòrum (angular wall) and in the Praetorium (southeast tower with entranceways, vaults and pilasters).
Mondays open: Roman Model, Cathedral and Museum, Mèdol Quarry, Francolí River Paleochristian Complex, Museu Bíblic Tarraconense (Biblical museum) and Chapel of St. Paul + 3 June-26 August: the Walls (Archaeological Promenade), the Praetorium and Roman Circus, the Roman Amphitheatre and the Local or Colony Forum
