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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
