José Sandín

Rather beautiful though lesser known park, in the neighbourhood of Puerta de Toledo, though close enough to the river and working class areas to the south of Madrid.

Lots of things to do around it, including some nice outdoor bar with ambient music.

One of three archaeological museums in the area. On itself a trip throughout the ages, from Prehistory till the late 17th Century. The Renaissance building that contains it, with its frescoes in the domes, is a work of art on its own right.

It offers didactic activities for children and adults alike, and truly remarkable temporary exhibitions in its patio every now and then.
