The Ćiastel de Tor, San Martin - Studies have dated San Martin de Tor back to Roman times. A number of paths and locations found in what is now the town centre can be traced back to the practice of subdividing land into quadrilateral lots, which was typical of the era. Also, it is believed that the word "quadra" (square in Italian), which was initially used as a term for a surface, was extended to the whole of the Badia valley (Gadertal in German). It was only later that the term "Gader" originally "Kaidra" – “Square”. was introduced. Today, the castle, which dates from the early 13th century, houses the "Museum Ladin".
