I have been searching for open museums this National Worker's holiday and thought I would share one that I have found, and can vouch for its interest.

Fundación Juan March
www.march.es

This is in the lovely Salamanca district and will be open from 10 a.m until 2pm according to whom I spoke to on the phone and their website.

There is an exhibit of the Brazilian artist TARSILA DO AMARAL
on now.

This museum/cultural center, as I have remarked in other posts, also has a series of free concerts and recitals.

Lunch nearby at El Séptimo restaurant will work out well, too. www.elseptimo.com

Enjoy!

On April 30th I hope to trek out ot the Museo del Traje ( the "dresswear" museum) as it also looks quite interesting.

In addition for this weekend:
FREE ADMISSION to the Prado on May 2.

Reopening of the Railway Museum on May 2. Since 1984, the museum has been located at Las Delicias Station, the oldest in Madrid. Inaugurated in 1880 by King Alfonso XII, it constitutes one of the most noteworthy examples of 'iron architecture' of the 19th century. It houses one of the largest collections of historic locomotives and travellers carriages in Europe. FREE ADMISSION THIS WEEKEND.

Enjoy, too, the railway park

… and don't miss, at El Séptimo, a dessert called 'tatín de mango'. Ummm!!

Hurray we have wondered when the train museum will re-open for our fall trip! Thanks! \/

Exactly revulgo.. you know my favorite dessert. I always order it at same time of my meal as once they ran out of it and I was devastated.. ( well.. not really.. but VERY disappointed!)

Lin, please go to the Museo del Traje. There are serious talks about closing it. It is a bit out of the way, and small, but they have some gorgeous things there.

Bye, Cova

Yes, lin, I had heard that too, that they were seriously considering closing it since it just doesn't get much traffic at all. And while in that general vicinity, you might want to check out the Pre-Columbian art in the Caribbean exhibit at the Museo de América.

Enjoy your trip.

What? closing it? that would be sad.
I really enjoyed it.

New temporary exhibition in the Museo del Traje: "Spike heels. Fascination and seduction". From May 8 to August 30
