The park backs onto the San Lorenzo Cathedral and covers an area of 40,000 square metres. In ancient times, several waterways met in this area and then flowed into the canal. For eight centuries, the gallows of Milan towered here; above the Vettabia canal there was the bridge, where those condemned to be hanged passed. It was the zone where hide tanners called vetraschi had their workshops, and from which came the name of the square. Animated bars that are ideal in summer for an outdoor aperitif surround the park, planned after the war by architects, Bagatti Valsecchi and Grandi.
