Known as the Gothic Quarter, the Barri Gòtic is Barcelona's oldest district. A former fortified Roman settlement, the maze of atmospheric narrow streets house spectacular Gothic buildings and cathedrals, marking the city's heyday during the 14th and 15th century. There are many significant sights to visit in this pedestrianised quarter, the most illustrious being the immense Gothic Cathedral La Seu, with its breathtaking façade and serene cloister. With an assortment of shops and delightful sidewalk cafés in a picturesque setting, the Barri Gòtic is a worthwhile day out. To view the remains of this ancient Roman city, Barcino, visit the Museu d'Història de la Ciutat in the Palau Real, where Roman streets are still visible in the extensive cellar.

Many people forget that Barcelona is not only a big bustling city and cultural centre, but that it's bordered by the Mediterranean Sea, awarding the coastline with a string of attractive beaches, an ideal diversion after excessive sightseeing and shopping. Visit the popular Barceloneta Beach only ten minutes from the city centre where there are a selection of beach bars, cool down with a refreshing swim and marvel at the bizarre architecture of Homenatge a la Barceloneta, by Rebecca Horn. For more peace and quiet during the summer season venture a bit further to either Icaria, Mar Bella or Stiges Beach, where the crowds would have dissipated.

FC Barcelona, one of Europe's most loved football teams, has an informative museum with displays of photographs, documents, memorabilia and trophies, covering over a century of club history, that will satiate the fascination of even the most dedicated fan.

With a panoramic view of the stadium from the grandstand, visitors can get a taste of the heady atmosphere of a FC Barcelona match on their home ground. The museum also has an official store where club jerseys, caps and accessories can be purchased.

Barcelona's famous architectural son, Antonio Gaudi, left his mark on the city nowhere more prominently than in the gardens of the Parc Guell. The park, sited on Camel Hill offering splendid views of the city, was originally planned to be a garden city suburb, but only two houses were completed before it was turned into a public recreational park. The gardens are festooned with examples of his work, including flights of stairs, columns and a plaza decorated with mosaics. The pink fairytale house standing at the entrance to the park was once home to Gaudi and his niece, but is now a museum containing some Gaudi-designed furniture, décor, drawings and portraits of the architect.

A celebration of the life and work of world-renowned Catalan surrealist sculptor and painter, Joan Miró, the Joan Miró Foundation in Barcelona houses the majority of the artists work including paintings, drawings, sculptures and textiles. Distinguished by his use of primary colours, simple lines and two-dimensional geometric shapes, Miro refused to be categorised into an established art movement and as a result continued to create unparalleled works of art. Another product of original artistic genius from Barcelona, the works of Miró at the Joan Miró Foundation allow visitors to further delve into the unrestrained creative energy of this exceptional city.

Another fantastic construction by the creative genius Antonio Gaudi, Casa Mila, commonly known as La Pedrera, was the last civil work that Gaudi undertook before dedicating all his time to the assembly of La Sagrada Família. The building demonstrates the signature style of Gaudi with elaborate designs, globular shapes, assorted sculptures, colourful tiles and intricate details. Built between 1906 and 1912, the distinct architecture of La Pedrera and her counterparts was unconventional and unheard of in the popular Spanish architecture of the time. Renowned for its attractive rippled façade, visitors to La Pedrera can also witness a spectacular panoramic view from the rooftop as well as some eccentric signature style chimneys.

The most famous street in Europe, the wide tree-lined boulevard known as La Ramblas, is a long continuous pedestrian avenue that changes names five times as it cuts through Barcelona's 'old city', the Barri Gotic, from the Placa Catalunya to the city's port. It is lined with cafes, restaurants and shops, and is usually thronged with leisurely walkers enjoying the sights and sounds. Whilst walking around it is worthwhile to note some attractions along the way, including Gaudi's Guell Palace, his first big architectural assignment, and the pretty square, Placa Reial.

One of Catalonia's most intriguing landmarks, the bizarre Church of the Holy Family designed by modernist architect Antoni Gaudi, was started in 1882, but it remains unfinished and an object of controversy. Gaudi worked on what was considered his masterpiece until his death in 1926, imbuing the structure with his characteristic fantastic Art Nouveau styling. Work has continued sporadically since, but Gaudi left no plans for its completion and the continued construction has run rampant. The church site stands at the junction of Marina and Provenca streets in the central city area.

Montjuic is a hill overlooking the city centre of Barcelona on which are sited some of the city's show-pieces, including the main sites of the 1992 Olympics; the Poble Espanyol (a replicated Spanish village displaying art and architecture); the Joan Miro museum; and the National Art Museum of Catalonia. There are also some leisure attractions and cool green parks festooned with fountains, popular for strolls on summer evenings. The magical fountains of Montjuic are a popular attraction that entertain on summer evenings with displays of light, colour and music.

The castle is also home to the Military Museum as well as the Museum of Comics and Illustration, a great place for the kids to enjoy looking at the favourite comic book.

One of the most visited sights in Catalonia is the monastery at Montserrat, 35 miles (56km) northwest of Barcelona. The monastery is surrounded by strange rocky crags and caves, and was founded in 1025 to celebrate local visions of the Virgin Mary. It has become one of the most important pilgrimage sites in Spain, sitting atop a 4,000-foot (1,200m) high mountain and housing about 80 monks. Its main claim to fame is a 12th century Romanesque wooden sculpture of a black Virgin Mary known as La Moreneta, which thousands come here to see and touch. The monastery on its mountain perch is reached by cable car.

The Barcelona Museum of Contemporary Art is situated in the once shabby Raval district just off La Ramblas. Over the years its front plaza has become synonymous with international skateboarders, being fondly known as the famous MACBA, drawing skaters and creatives from around the world to unite against the backdrop of its chic white building. Being a work of art in itself, the Museum of Contemporary Art was designed to monopolise on natural light and the cool airy interiors confidently hold the works of modern art luminaries such as Basquiat, Klee, Tàpies and Barcelò. A perfect union of two art forms, MACBA and her throng of talented skateboarders is a sight to be experienced.

Located in the centre of Barcelona, the Parc de La Ciutadella is a great place to spend a sunny summers afternoon relaxing under a tree with a book, a picnic and the family. Featuring a lake where visitors can hire a small rowboat, exploring the park and being out on the water is a fun way to unwind. The park also features a fountain, statues, a few museums, and the Barcelona Zoo, which is a good place to head when the novelty of rowing a boat has worn off!

This UNESCO Biosphere Reserve of Parque Natural de Barenas Reales offers visitors the chance to walk through a moon landscape.

Visitors to the park can also see the ruins of Peñaflor Castle, while the nearby towns of Arguedas and Valtierra have a variety of attractions and historical sites.

On Carrer Montcada, a street known for its elegant medieval structures, two palaces dating from the 15th century have been converted into the Picasso Museum, home to one of the most complete collections of works from his youth and formative years as an artist.

The collection includes a number of childhood portraits and paintings, as well as engravings, drawings and art from his Blue and Rose Periods.

The mock village of Poble Espanyol is an outdoor open-air architectural museum featuring over 35 workshops where visitors can see 20 different types of craftsmanship at work.

Barcelona's second landmark hill is Tibidabo, about four miles (6km) northwest of the city in a wooded range that forms a backdrop to the city. Tibidabo can be reached by funicular, and is particularly popular at weekends with locals because it is home to the Parc d'Atraccions, an amusement park with some thrill rides and renowned house of horrors.

There are four beaches within the town itself and numerous others flanking Tossa on either side.
