Carrer Major street and Plaça de Sant Antoni square (formerly Plaça de la Constitució) are the oldest and historic centre of Caldes. This is why it is on this square that Caldes d’Estrac’s first Town Hall was located. The people who lived here were fishermen, seamen or farmers. In 1882, according to Joaquim Salarich, these lands produced wine, some grains, legumes, carob beans, oranges and vegetables. The town’s industry was limited to fishing, which was performed by men with 18 boats in winter and 20 in summer, while the women devoted their time to the art of blond and bobbin lace.
At the end of Carrer Major, on a crossroads with Carretera de Sant Vicenç, attached to the slope, you can see half a circular lime kiln with an inner diameter of 3.40 metres and a height of 4.50 metres dating from the 17th century, when it stopped working. The other half was damaged and destroyed during the construction of Escales del Fondo (in the late 1960s). In 2009, Caldes Town Council decided to preserve these remains of the pre-industrial era as a first step in the recovery of unique archaeological items. Right in front of it, towards the east, you can see the hill of Puig Castellar, with Torre dels Encantats and the Iberian settlement, which belong to the town of Arenys de Mar.
