With their narrow passageways and cobblestone streets, picturesque Girona and Jerusalem’s Old City share more than just a certain outward appearance.

As early as the 12th century, artists from this Catalan city portrayed Jerusalem and its Jewish residents in a magnificent tapestry depicting the creation story. And Girona’s most illustrious Jewish resident, Moses ben Nachman, also known as the Ramban or Nachmanides, traveled to Jerusalem for his dying days. In letters to his kin, the Ramban describes his longing for his family and rich Jewish life in Girona in the face of a desolated, 13th century Jerusalem left in ruins.

These are just some of the many fascinating bits of information served up by the Centre Bonastruc ca Porta, a leading educational and cultural foundation named for the Ramban in Girona’s restored Jewish Quarter.

The Call, as the quarter is known in Catalan, dates back to the year 890 when 25 families from the surrounding region moved into former houses of clergy near the city’s large cathedral. Over time, the Jewish district expanded to include a larger area that once housed more than 300 Jews. In return for financial tribute, the Spanish kings protected the Call, as it did all other Jewish communities under the Crown of Catalonia and nearby Aragon. The quarter’s main thoroughfare was Carrer de la Forca, or La Forca Street, which is where the Centre Bonastruc ca Porta now stands.

The Centre represents efforts of late to reclaim the region’s Jewish heritage. Located about 40 minutes north of Barcelona, the Centre is also the headquarters for the Network of Spanish Jewish Sites-Roads of Sepharad. It coordinates a wide spectrum of activities, run almost entirely by and for non-Jews committed to furthering awareness of a lost community that left deep impressions on Spain’s culture and economy.

Until recently, Spain had preserved relatively few examples of architecture that testified to the presence of Jewish communities in Catalan cities throughout the Middle Ages. But in the 1970s, private investors began renovating some buildings within the Call. And by 1990, the Girona City Council had managed to purchase the various buildings that now make up the Centre Bonastruc ca Porta. It was another 10 years before part of its permanent exhibit opened to the public in July 2000.

Within its walls, you’ll find exhibits and cultural activities, concerts and theater productions. There are also lectures, round-table discussions, classes for tour guides, courses on medieval Spanish Jewry and kabbalah, relations between Jews, Christians and Muslims and modern Hebrew. You can also take guided tours through the Nachmanides Institute for Jewish Studies, which hosts visiting scholars, and the Museum of the History of the Jews. This relatively small museum depicts Girona’s Jewish history, including its tragic fate with the Spanish Inquisition in 1492.

Despite popular understanding, the terror actually began 100 years earlier with a pogrom on Tisha B’Av 1391. It led to innumerable conversions, seizure of property and the closing of synagogues throughout Spain well before final expulsion.

Although Girona was once home to two synagogues that were easily identified, its last synagogue’s location is disputed. It was positioned intum callum judaycum or within the Jewry, in a discrete spot inside the Call that was maintained until 1492. Some say it was based in the very building now occupied by the Bonastruc ca Porta Centre, where Nachmanides may have himself prayed and studied Kabbalah. A bill of sale signed by the Council of the Jewry in 1492 shows the building was a fairly large structure containing two batei midrash — one for men, another for women — as well as mikvahs and a hospital.

That is just one of the more than 1,200 documents pertaining to Girona Jewry that the Centre has identified in two city archives. Other papers include manuscripts written by the Catalan kabbalists, many of whom lived in Girona, commentaries of Ezra ben Solomon on the “Song of Songs” and treatises of Ariel of Girona on prayer.

The Centre also preserves archaeological remains from tombs and long-abandoned funeral stones that were left on the city’s Montjuic, or Jewish mountain, where the cemetery once stood. You’ll see such treasured remnants of Girona’s lost community within the museum. Some are poignantly exhibited on a dramatic latex floor displaying photos of green fields and yellow wildflowers — exactly how they were found.
