The northern boundary of el Call has not been clearly defined by historians. It is documented that the old street of Carrer de la Volta (the Vault) was not a boundary, because on both sides of the street there were properties owned by Jewish people. In the north, the properties bordered with some orchards and properties owned by Christian people. There was the important Escola de la Seu. However, it is difficult to believe that the axis of Santa Eulalia and Sant Sever to the Roman walls was always outside the limits of el Call. Number 1 in Sant Sever supported the vault that gave its former name to the street, and it lead to an old dead end street that was called "under the Vault” (sota la Volta). Before the riot of 1391 David Bellcaire, who as a convert, changed his name to Miquel Lupetti, and was the owner of the house. David de Bellcaire was also owner of the building at the entrance of Carrer de Sant Domènec, where the gatekeeper lived and where the Kosher butcher was. He was the son of Isaac Bonjuha Bellcaire, one of the secretaries of the community in 1349, and was related by marriage to the traditional and influential family Cap-Forn. This family is a good example of how the Jewish community in Barcelona related with strategic marriages.
