In the past it was one of the thirty-six castles of nearby San Miniato but today this characteristic town, which is not far from Castelfiorentino, still conserves some traces of its medieval architecture. For example the brick bell tower of the Church of Saint Maria Assunta, where the evocative Annunciazione by Neri di Bicci is still displayed and the Church of Saints Lorenzo and Barbara which dominates the small central square of Castelnuovo with its characteristic brick facade.
