Summer is the best time to travel in Switzerland.
Locarno’s Piazza Grande
The Lombard architectural style is used to create a 700-meter-long series of aesthetically pleasing porticos that serve as the commercial and dining district of Locarno. This street view is particularly active in the summertime when "Moon & Stars" and the International Film Festival are taking place. The Visconti Castle, the numerous churches of the Città Vecchia (old city), the lakeside, and the significant San Vittore church in Muralto are just a few of the significant locations in the historic center that are reachable from Piazza Grande.

Due to the retreat of the lakeshore, which had previously brushed the homes, Piazza Grande was constructed in the 700s. The traditional cobblestone river pavement was created in 1825.
