Fő utca is the arrow-straight ‘Main St’ running from Clark Ádám tér through Víziváros; not surprisingly, it dates from Roman times. At the former Capuchin church you can see the remains of an Islamic-style ogee-arched door and window on the southern side; it was used as a mosque during the Turkish occupation. Around the corner is the seal of King Matthias Corvinus – a raven with a ring in its beak – and a little square called Corvin tér.
Here you'll find the delightful Lajos Fountain (Lajos kútja) dating from 1904. The Eclectic building on the north side at No 8 is the Buda Concert Hall (Budai Vigadó). To the north the Iron Stump is an odd-looking tree trunk into which itinerant artisans and merchants would drive a nail to mark their visit in medieval times.
