Museum with Spanish coins and banknotes made in the factory
I was really looking forward to going however all the signs are in spanish which was expected but the way they were written was pretty boring and there was so much writing I just couldn't read everything as struggled to read them and I preferred to just look at the coins. There are a lot of coins dating back to the ancient coins (less itneresting for me) right up until today.
Well worth a visit, you can mint your own token at the end for 3 euros (if the guy isn't busy he might actually explain things so you could understand). We did this to add to our collection of souvenir coins
