Area naturale protetta di interesse locale Monte Castellare, Local interest nature reserve in San Giuliano Terme, Tuscany, Italy
The Area Naturale Protetta di Interesse Locale Monte Castellare is a protected space in San Giuliano Terme with walking trails through olive groves, garrigue, and wild meadows. The grounds contain archaeological sites from Etruscan and medieval times as well as ruins of the 19th-century Villa Bosniaski.
The grounds show traces of Etruscan settlements that developed over 2000 years ago and was later used as a strategic point on a trade route between Pisa and Lucca. A Polish naturalist built Villa Bosniaski around 1870 on this property.
The name Monte Castellare refers to a castle that once stood here. Today visitors use the space for walking and nature observation, with olive groves reflecting the traditional farming practices of the region.
The Buca delle Fate cave has five entrances on the south-western slope of Monte Castellare, reachable from the old road to Villa Belvedere. The summit ruins lie at 253 m, and the quarries on the slopes extracted limestone and white marble. Excavations begun in 1988 by Adriano Maggiani with the Gruppo Archeologico Pisano are currently stalled.
The Buca delle Fate, also called Buche Tane by locals, is the largest karst cave system in the Monti Pisani, reaching 185 metres of depth and 500 metres of passages. Its five entrances open on the south-western slope of Monte Castellare, near the old road to Villa Belvedere. The area holds over 35 orchid species.
