The workshop venue is located in the city of Guadalajara, in Castilla-La Mancha.

Guadalajara is a well-appointed city, with ample green areas and a range of services to meet the needs of its people.

Its modern installations have made it possible to attract leading sports events and congresses that in turn have raised the city profile both at the regional and national levels.

Its excellent cuisine, based on high calorie dishes suited to the climate of the region, deserves special mention. Amongst its specialties, there is roast lamb and roast kid goat accompanied by sauce, a dressing of aromatic herbs soaked in vinegar. For dessert, the star product of the city is bizcochos borrachos (alcohol soaked sponge cake), or honey from La Alcarria, with Designation of Origin since 1992. The visitor has a wide selection of dishes and restaurants to choose from, with something for even the most discerning taste.


The city is located near Madrid, Alcalá de Henares and Toledo (Castilla-La Mancha), very interesting places to visit if you have time.

If you prefer the country side and nature instead of large cities, you can also discover many beautiful routes for hiking and walking in Guadalajara region or in Madrid´s mountain range:
