El Regajal is a unique estate located in Aranjuez, on the southern limit of the Community of Madrid, known since the mid-nineteenth century by all the entomologists in the world. In their lands live 77 of the 225 species of lepidoptera of Spain, interesting not only for their number but also for the rarity of some of them.

The current ownership of the estate has made the entomological research activities compatible with a wine project of high quality, which gives the chance to the public to approach the culture of wine.
