The piazza has also been hit by floods in modern times: the three most recent major events took place in 1993, 2000 and 2014, the level of the lake in 2000 rising to 197.58 metres from its usual 193 metres. At times like this, the only way to reach the Piazza Grande is by boat or by walking along a specially built pier that crosses the square. By the way, have you ever wondered what those rails are doing in the Piazza Grande? It's a good question, because anyone who knows Locarno knows that it doesn't have trams. But that wasn't always the case: in the early 20th century, Locarno was something of a railway hub. The city had a tram, a railway line (the Valmaggina) went up the Maggia valley, and another line (the Centovallina) went all the way to Domodossola – and still does. The tram service was discontinued in 1960, followed by the Valmaggina line in 1965. The urban section of the Centovallina was put underground in 1990, since when the Piazza Grande has definitively been train-free. At that point, the piazza was used as a car park until the beginning of 2000.
