Horta-Guinardó is located on the north-east of the city, between Gràcia and Nou Barris. It is bounded by L’Eixample, Sant Andreu and Sant Martí to the south, and –through the Collserola mountain range- by Sant Cugat and Cerdanyola del Vallès to the north. In the neighbourhood of Horta –independent borough until the early 20th century located on the north of the present district- we find the famous Laberint, the oldest park in Barcelona.
