Park- Guell I would show my classroom when we talk about spanish art. Gaudi is a very famous spanish artist and Park guell- along with Sagrada familia, casa de batllo, casa mila etc. are some of his most famous work. This tour of Park guell shows the entrance which leads to many other aspects of his crazy modern art.

This virtual tour is of a part of La Alhambra in Granada Spain. This also fits into spanish culture but for Muslim art. It is a Moorish palace and it fits into Spanish history and the cultural art and how different parts of Spain were influenced by the muslim culture.
