Who are we?

Cosa de 3, S.C. is a civil company founded by Beatriz Lerga Echarri, Immaculada Portella Padró and Montserrat Vives Valero.

We are united for our passion about miniatures and the will to make them widely known, and, specially, the will to make Barcelona an unmistakable spot in the world’s miniature calendar.


What do we want?

After several years participating in the organisation of a similar event, we decided to start this new adventure with a  professional structure.


We want to make a Fair where visitors and exhibitors feel welcome and even pampered, with a personal, direct , and warm approach. We think this is compatible with a Fair where the professional miniaturist can make business, the collector can find quality pieces, and the maker can find techniques and materials. 


Until our 2017 edition, Barcelona Miniaturas took place at the Hotel Hesperia del Mar. It is located in C/Espronceda 6, just a short walk away from the beach and  a main shopping mall, and well communicated with the centre with buses and metro. It’s a four star hotel, and in spite of belonging to a big Hotel chain, it is run by a team of very good professionals who always walked the extra mile to make us feel welcome and at home.

However, we decided to move to a more central location, to make it easier for visitors and exhibitors alike to come to our Fair. After an intensive search, we decided to make our Fair at the Hotel Catalonia Plaza Catalunya, at Bergara Street, 11. It is a very beautiful hotel, formerly a palace designed by one of Gaudi’s teachers, located in the heart of Barcelona, and it has got all the amenities of a four star hotel.
