Once a 14th-century house of the Jewish weaver Jucef Bonhiac, this small visitors centre is dedicated to the history of Barcelona’s Jewish quarter, El Call. Glass sections in the ground floor allow you to inspect Mr Bonhiac’s former wells and storage space. The house, also known as the Casa de l’Alquimista (Alchemist’s House), hosts a modest display of Jewish artefacts, including ceramics excavated in the area of El Call, along with explanations and maps of the one-time Jewish quarter.
