Piazza della Loggia is fine example of Renaissance piazza. The construction of eponymous Palazzo della Loggia (current Town Hall) began in 1492 under the direction of Filippo de' Grassi and completed only in the 16th century by Sansovino and Palladio. Vanvitelli designed the upper room of the palace (1769).
On the south side of the square are two 15th–16th century Monti di Pietà (Christian lending houses). Their façades are embedded with ancient Roman tombstones, one of oldest antique lapidary displays in Italy. At the centre of the east side of the square stands a tower with a large astronomical clock (mid-16th-century) on top of which there are two copper anthropomorphic automata which strike the hours on a bell. On May 28, 1974, the square was targeted by the terrorist bombing.References:
The Historic Sausage Kitchen of Regensburg (Wurstküche) is notable as perhaps the oldest continuously open public restaurant in the world. In 1135 a building was erected as the construction office for the Regensburg stone bridge. When the bridge was finished in 1146 AD, the building became a restaurant named Garkueche auf dem Kranchen ("cookshop near the crane") as it was situated near the then river port. Dockers, sailors and the staff of the nearby St. Peter cathedral workshop were the regulars for the centuries to come. The present building at this location dates from the 17th century, but archaeological evidence has confirmed the existence of a previous building from the 12th century with about the same dimensions.
Until ca. AD 1800, the specialty was boiled meat, but when the family who currently own the restaurant took over in 1806, charcoal grilled sausages were introduced as the main dish offered. The kitchen still operates today and serves 6,000 sausages to guests daily.
