In mid nineteenth century, with the beginning of industrialisation, Barcelona began to grow out off the city walls, extending the living and working space for the fast-growing population. The Eixample district, with its large straight streets and its modernist architecture, testimonies a time of progress and prosperity that characterized the city trough the last decades of the 1800's and the beginning of the twentieth century.
A visit to this quarter must include a stroll along Passeig de Gracia, a beautiful avenue, where you can find two of the most famous monuments of Barcelona's architect Antoní Gaudì. The Casa Milà (also known as La Pedrera) and the Casa Batlló can be admired from the street and visited inside. But those two houses are not the only ones to captivate the interest of those who love architecture. The Passeig de Gracia, that connects the medieval city (starting at Plaça Catalunya) to the Gràcia district, is lined with admirable buildings, chic boutiques and great restaurants.
Further east, the Sagrada Família cathedral , also projected by Gaudì, is a place where is mandatory to go with plenty of time. Not far from the cathedral you can find the Hospital de Santa Creu i de Sant Pau, another example of modernist architecture.
Is advised to book the visits online as the lines for buying tickets are long and some times is even impossible to get tickets for the same day.
