Sarrià –neighbourhood in the district of Sarrià-Sant Gervasi bounded by Vallvidrera- was an independent borough until the early 20th century. Still today, inhabited by well-off families, its old part keeps the charm of small villages. On the other hand, the neighbourhood of Pedralbes, in the district of Les Corts, is the most luxurious residential area in Barcelona, with mansions along, for instance, Pedrlbes and Pearson avenues.
