Not only are there many tourists, but it is also a good place for Madrid citizens to enjoy their time. There is a man-made lake. The magnificent statue on the East Bank of the lake is Alfonso's 12th century monument. The two groups of statues are the army image carved by Jos Montserrat (north side) and the Navy image carved by Mateo Inurrria (south side). It's also great to sit and watch the boating on the lake.
