Museo Geominero

While the main reason to visit this museum is its collection of rocks, crystals, gems and fossils, the building itself is a must see for its beauty and splendour. Its huge collection is presented in a very archaic way, in the Spanish language only, but I enjoyed it nevertheless. It can get very busy with rowdy teens as it is frequently visited by schools.

Collection of minerals and fossils from Spain and the whole world. Hundreds of objects. Quite a collection. It is located at a university building. Entry is free, but security check is conducted. The big room is impressive.

Wow. Just wow.

We are hobbyist field collectors from UK and generally find mineral museums to be a bit of a jumbled mess, or missing the high quality systematic/locality based approach.

This museum was exceptional, great specimens of both fossils and minerals, lots of info and was free to enter. We spent a couple of hours and I could have spent more, but we were only visiting Madrid for the day.

Was great to see some specimens from our home turf, and one from a locality I have visited in the UK

Only gripe was the majority was not translated, but we can not expect this as visitors to another country.

Would highly recommend visiting!

This museum has an impressive collection of fossils and minerals. The building itself is an architectural jewelry. Has free entrance and is one of those places you can go with your kids and they will not get bored.

Very nice small museum that can be covered in less than a couple of hours. And it’s completely free!! Amazing collection of a wide variety of geo mineral samples from around the world. Unique rock collection. I just wish if they could have better lighting to showcase their collection well. Also, the actual rocks and fossils museum is on the first floor. The directions were not so clear. But you can always ask friendly smiling staff.

A lovely museum! Kids loved it❤❤❤ and it's free. thank you so much!

A diverse collection of rare earth metals and minerals. It is a wonderful learning experience with just a cursory walk through. Repeat visits are a must!!

Best museum of Madrid!!! A vast amount of minerals and fossils. Such a gem.. literally!

What an absolutely amazing museum in a stunning building. Very extensive collection of fossils and minerals (although not many truly exceptional pieces). The stained glass roofs are incredible. And it's all free! Look out for the grumpy security guard who will demand your passport/ID and put you through an airport-style security check. Why? I don't know - I guess gotta generate employment one way or another :)

It’s free and there are pretty rocks. No English text though.

We visited in April 2023 and thought it was amazing!! Most say it's a great place to bring kids, it's fascinating for adults also. My wife and I were constantly saying "Oh my, check THIS out!", and the building is incredible also. I would say it's a must visit in Madrid, can cover it in an hour or two.

It is an amazing place where you can go back in time and discover many interesting things about the history of our planet. Allow yourself as much time as you can, it's worth it.

Amazing museum! Located in an ancient building, the interior of which also deserves attention (what beautiful stained glass windows there are!). The exposition is also excellent - fossils and samples of various rocks and minerals, including rare and expensive ones (diamonds, gold). It will be interesting for both adults and children. The entrance is free! Works on weekends!

Amazing experience that reminds me of natural history museum in London but this one is focused on minerals. It's free to visit and has a fantastic display. If you're a fan of colourful rocks like me it's a must to see.

Free entrance.
In the beggining it was looking very poorly, but after passing the doors there were hundreds of minerals on 3floors.
Some of them historical with parts of animals. Some simply beautiful.
Nothing in English but still very enjoyable.
Building from the inside is beautiful. Roof and some of the windows are astounding.

It was nice to visit this museum for free (on the particular day). I am not a fan of it, but it was interesting. There is an issue to enter the museum for families with a kid's trailer. We couldn't find a way to enter easily, so i just carried our trailer upstairs. Furthermore it is just not possible to go to the next floor inside due to a specific spiral staircase.

An impressive collection of ores and fossils. A well-designed museum, where you can easily spend a whole day admiring the brilliance or mystery of each ore or fossil. I highly recommend especially to geology and archeology enthusiasts.

This museum is a must for all those who love geology, rocks, fossils and crystals. The exhibits are well categorised by their chemical formation (silicates, elements, etc) and there are a number of varieties for each rock and crystal. It is worthwhile visit
There is also a section showing the various rypes of cuts used in gemstones. In January 2018 there was also a highly interesting section on amber, however I don't know if this is a permanent exhibit. Highly recommended. Entrance is free but a travel document / passport is required.

Excellent place to look samples o metals, fossils, volcanic ashes, etc… one the best thing that it’s free.

Amazing building housing a good collection of rocks, minerals and fossils. Information sheets are available in English and Spanish
