Gammarelli

Gammarelli began in 1798 when Giovanni Antonio Gammarelli opened the business, originally serving Roman clergy. After Giovanni, his son Filippo took over the shop, and then Filippo's son, Annibale, succeeded his father. In 1874, Annibale moved the shop from its original location on the Via del Baulari to its current storefront on Via Santa Chiara 34, where it is surrounded by other vendors of church goods in an area that has been compared to London's Savile Row. It is located in the same building as the Pontifical Ecclesiastical Academy. Annibale's sons Bonaventura and Giuseppe renamed the shop "Ditta Annibale Gammarelli" in honor of their father. Bonaventura's son Annibale took over from his father, followed by the sixth generation of the family: Maximillian, Lorenzo and Stefano Paolo.

The reforms of the Second Vatican Council regarding clerical dress, the establishment of the Iron Curtain separating priests and bishops in Eastern Europe from the West, along with a decline in the number of priests in markets like the United States, led to a decline in business for the tailor beginning in the mid-20th century. It then began cutting everyday suits and offering wool-polyester and cotton-polyester blend fabrics to appeal to Americans. Business also increased after John Paul II mandated priests in Rome to wear the clerical suit or cassock in the early 1980s.

The store was honored by being recognized as a historical workshop by the mayor of Rome in 1998 and added to a list of Rome's historic shops in 2000. The clothier launched its first website in 2012, and in 2016, the sixth generation of the Gammarelli family assumed leadership of the business. The store continued to manufacture and deliver orders to customers through the COVID-19 pandemic, and as of 2024, Alessia Gammarelli is the owner and manager, the first woman from her family to manage the establishment. It is counted among the oldest family-run businesses in Europe.

Gammarelli produces multiple types of clerical clothing. These include vestments for the celebration of Mass and other liturgical functions, such as chasubles, mitres, and episcopal sandals; choir dress for those clergy attending but not participating in the liturgy, such as zucchettos, mozzettas and surplices; as well as house cassocks and saturnos along with sweaters and suits for everyday non-liturgical wear. The specific type of surplice worn by the papal master of ceremonies and preferred at the Vatican, an off-white garment with subdued bands of embroidery, is sometimes referred to as a Gammarelli surplice. The shop is also a vendor of clerical shoes, in black for common priests and in red for cardinals.

General liturgical supplies, such as altar cards and chalices, are also sold by the retailer. Ornamental drapery for special liturgical occasions was also produced by the firm, such as for the 1899 reconsecration of Santa Cecilia in Trastevere.

Gammarelli is a vendor of the specialized attire of cardinals, and they have clothed notable cardinals such as Francis Spellman, Walter Kasper, Friedrich Wetter, and Joseph Bernardin. Oftentimes newly-appointed cardinals do not buy their own vestments, but rather are given them by family and friends who buy them from Gammarelli. The retailer is one of the few remaining manufacturers of the galero, which is no longer worn by cardinals after its 1969 abolition but is still suspended over the tombs of deceased cardinals. The costuming for Otto Preminger's 1963 drama The Cardinal was also provided by the family.

The shop also sells regalia for Papal knights, such as the Order of Malta, the Order of St. Sylvester, and the Order of Saint Lazarus. It has been the official vestment retailer for the prayer league of Blessed Charles I of Austria since 2024.
