The former Church of the Tau is located in the historic center of Pistoia. The church is dedicated to the cult of Sant'Antonio Abate, from which the name of the brotherhood of the Tau derives. In fact, the representations of Sant'Antonio refer to the long "T" -shaped stick and the presence of a pig at his feet. These two elements led to the birth of the emblem of the order of the Tau: the Greek T and the fat of the pig for the treatment of diseases. The Church was built in the mid-fourteenth century and consists of a covered garden, the convent with the internal cloister and the church with the crypt. Over the centuries the building was abandoned and suffered a lot of damage. Only after the restorations in the 1980s was it possible to recover the architecture. The church still partially preserves the cycle of frescoes made by Niccolò di Tommaso, a Florentine painter, together with Antonio Vite from Pistoia. The depictions of the frescoes relate to the history of the Old and New Testament with the life of Sant'Antonio Abate. Today the church has been deconsecrated and is open to the public for guided tours and temporary exhibitions.
