Starting down on the river, site of the old tanneries, the tour is a gentle stroll through the lower town and the alleys of the Sa Costa quarter, including the fascinating Museo delle Conce, or tanneries museum, and the Cathedral. The tour finishes at the ruined Castello Malaspina, stunningly sited at the top of the town.
At every stop, Alessandro, a local English-speaking guide, will explain a bit about what you are seeing. Entry to all museums and the castle is included in the tour, which lasts 3-4hr.
Alessandro fills you in on the architecture and history of the various buildings, provides historical context, and is there to answer all questions. A multilingual polymath with extensive experience in the tourism sector, Alessandro lives just outside Bosa.
