Arriving from the Via Cassia you catch the very first glimpse of Abbadia. It appears to be a modern town with wide, tree-lined avenues, but things change when you reach the town centre; it opens into a charming, atmospheric village, one of the loveliest places in Tuscany.
In the heart of the village is the San Salvatore Abbey, founded in 762 by the Lombard Duke Ratchis. The historic Bibbia Amiatina, an incredible example of an ancient manuscript, is held here. The Lombard crypt is also stunning, presumably dating back to the 7th century B.C with 34 columns.
You can reach the Castle via three streets that are more or less parallel to one another. The Santa Croce church (dating to 1221 but rebuilt in the 19th century) and Sant’Angelo church (1313, now a private home) are also found along these streets.
Palazzo del Podestà, Palazzo del Popolo and many other medieval buildings are equally as unmissable.
The mining complex near the town is of particular historical interest. Mined from 1897 until the 1970s, the mine bears witness to the pivotal changes in 20th-century Abbadia San Salvatore. The unused mine has been converted into a Mining Museum focusing on the geology, mining history, tunnelling, metallurgical work and the daily life of the miners. Outside the museum you can see one of the narrow-gauge convoys that were used in the tunnels.
