From the Roman city only the city walls have remained within the houses located between Carrer de Banys Nous and the Arc de Sant Ramon del Call. The Roman streets are: Carrer de la Volta (currently Sant Sever and Baixada de Santa Eulàlia), Sant Domènec and Sant Honorat, which was the old decumani minori, and carrer del Call, the former cardo maximus, which led to the Roman gate. In medieval times, its direction was slightly diverted due to the construction of Castell Nou (New Castle). In this house, whose owner was David de Bellcaire, a member of the Jewish community, there was a cul-de-sac, in modern times named Carrer del Mill. The street used to be known as "under the Vault", because it was covered by a vault. This vault was covering the current axis of Baixada Santa Eulàlia and Carrer Sant Sever.
