The Cathedral of the Holy Cross and Santa Eulàlia, or simply the Barcelona Cathedral, is the Gothic cathedral and seat of the Archbishop of Barcelona. Its construction began in 1298 on the site of an ancient Roman temple and took more than 150 years to be completed. Located in the centre of the historic Gothic Quarter of Barcelona, the cathedral is dedicated to the martyr Santa Eulàlia – the patron saint of Barcelona – who was tortured to death in late Roman times. Her corpse is buried under the main altar. Be sure to climb to the roof for a nice view of the city, and don't forget to visit the serene and beautiful courtyard, which is occupied by thirteen white geese representing the years of Saint Eulalia's life before she was martyred.

A fairytale castle nestled in the woods on the outskirts of the city. Despite bearing the mark of Victorian renovation, it still retains much of its medieval charm and it offers an interesting insight into medieval architecture and art.

Park Güell is one of Barcelona’s most iconic landmarks and a masterpiece of Antoni Gaudí’s creative vision. Perched on a hill in the Gràcia district, this enchanting park offers sweeping views of the city alongside whimsical architectural designs. Originally conceived as a residential project, the park is now a UNESCO World Heritage Site and showcases Gaudí's signature style, with colourful mosaics, curving structures, and imaginative sculptures. From the famous lizard at the entrance to the serpentine bench of the Terrace, every corner of Park Güell is a testament to Gaudí’s ingenuity and a must-visit for any traveller.
