Very nice place to explore and very interesting. Good views from the top. We went on a Monday, which by coincidence was free admission, but it is inexpensive anyway. Ticket office lady very informative.
A well preserved and restored defensive tower in the north of the Island. Great views out over the surrounding bays and harbors. Well worth a couple of Euros to get a bit of history and a slightly higher viewpoint.
One of many fortresses on the island this one is on the very end of the peninsular to Fornells looking out over the Mediterranean. It only takes about 10-15minutes walk from the centre of Fornells and its a short climb up a pathway to get there.
When we went it was free entry (Monday?) which was an added attraction but...
