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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
