Formerly known as Ajei (small village), San Bartolomé is one of the smallest municipalities of Lanzarote and one of the most unique, as it embodies the two faces of Lanzarote. To the north, there are fields of crops, while to the south you can see the volcanic origins of the Canary Islands. The village has several monuments that are worth a visit: the Casa Palacio del Mayor Guerra, declared a historical artistic monument, or the Casa Ajei, a beautiful example of the popular rural architecture of the time.
