From the centre of town, follow either Káptalan or Janus Pannonius utca towards the pristine Art Nouveau Peter and Paul Basilica (Mon–Sat 9am–5pm, Sun 1–5pm; 1200Ft includes Crypt; T72 513 080): topped with all twelve Apostles, it is built on an epic scale. Next door, you can visit the Episcopal Palace, whose interior styles span four centuries providing a veritable history of European design (guided tours only daily 9am–4pm; 2000Ft). Nearby at Szent Istvan tér 17 (in the gardens just below the steps to the cathedral), the Cella Septichora visitor centre gives access to a wealth of Roman and early Christian archeological remains (April–Oct Tues–Sun 10am–6pm; Nov–March Tues–Sun 10am–5pm; 1700Ft; T72 224 755). Pécs fell under Roman rule as the empire expanded into the Balkans in the second century, and became Christian with the conversion of the Emperor Constantine in 313 AD. The excavated rooms include the Peter and Paul burial chamber and a Christian cemetery site. Visitors can get a 360-degree view through glass panels placed above, below or on the side of the chambers.
