The Santa Barbara Fortress in Alicante is interesting to visit the museum, which tells about the history of education. There is a free guided tour. The views opening at the height of the fortress made a greater impression. You can take the elevator from the sea side. You can walk, which is more enjoyable. I went up twice and admired the beauties. There is a cafe and a gift shop on the top.
The fortress of St. Barbara on Mount Benacantil, which offers a beautiful view of the city. At least because of the view, it's worth going there. There is a small parking lot, there is an elevator (I do not know how many soo, we were by car). There are many historical and not so historical expositions, cafes with ice cream and coffee.
