Along the route there are many artistic, cultural and historical places of interest, including the region’s pretty medieval towns, monasteries, churches and ancient villas, such as the Medici villa in Agnano which used to belong to Lorenzo il Magnifico. The first town on the olive oil route is Calci. This old town is famous for its imposing monastery building which today is home to a natural history museum. From Calci, follow the Zambra stream to Mount Serra. This is the highest of the Pisan hills and from the top it’s even possible to see the islands off the Tuscan coast on a clear day.
