11 Best Sights in La Ciutadella and Barceloneta, Barcelona

Once a fortress designed to consolidate Madrid's military occupation of Barcelona, the Ciutadella is now the city's main downtown park. The clearing dates from shortly after the War of the Spanish Succession in the early 18th century, when Felipe V demolished almost 1,300 houses in what was then the Barri de la Ribera to build a fortress and barracks for his soldiers and a glacis (open space) between rebellious Barcelona and his artillery positions. The fortress walls were pulled down in 1869 and replaced by gardens laid out by Josep Fontserè. In 1888, the park was the site of the Universal Exposition that put Barcelona on the map as a truly European city; today it is home to the Castell dels Tres Dragons, built by architect Lluís Domènech i Montaner as the restaurant for the exposition (the only building to survive that project, now a botanical research center, not open to the public), the Catalan parliament, the city zoo, and two subtropical plant houses.  Be very careful with your belongings, particularly mobile phones, inside the park; keep all bags on your person. 

Catalan for “greenhouse,” this striking, plant-filled iron structure was originally built by Josep Amargós i Samaranch as a reception and lecture hall for the 1888 Universal Exposition. Despite being one of the outstanding moderniste buildings of Ciutadella Park, it bumbled along as a restaurant before falling into disuse in 2006, then inevitable disrepair. In December 2023, following months of restorative TLC, it opened to the public once again; becoming the first completed project in a vision to turn Ciutadella Park and its surroundings into a science and heritage hub.

This redbrick arch was built by Josep Vilaseca i Casanovas as the grand entrance for the 1888 Universal Exhibition. Similar in size and sense to the traditional triumphal arches of ancient Rome, this one refers to no specific military triumph anyone can recall. In fact, Catalonia's last military triumph of note may have been Jaume I el Conqueridor's 1229 conquest of the Moors in Mallorca—as suggested by the bats (always part of Jaume I's coat of arms) on either side of the arch itself. The Josep Reynés sculptures adorning the structure represent Barcelona hosting visitors to the exhibition on the western side (front), while the Josep Llimona sculptures on the eastern side depict the prizes being given to its outstanding contributors.

The last Barceloneta house left standing in its original 1761 two-story iteration, it’s fitting that CB1761 (its catchy moniker) is now used as an exhibition space to honor memories of the neighborhood’s past. The regularly changing photographic displays encompass social, political and artistic movements; recent retrospectives have included a photo-story of Picasso’s haunts in Barceloneta, and portraits of the (largely unseen) women integral to Barceloneta’s early-20th-century fishing industry. 

The Ciutadella campus of Barcelona's private Universitat Pompeu Fabra contains a contemporary architectural gem worth seeking out. It's two blocks up from the Ciutadella–Vil·la Olímpica metro stop, just beyond where the tramline begins. Once the hydraulic cistern for the Ciutadella waterworks, built in 1880 by Josep Fontseré, the Dipòsit de les Aigües was converted to the school's Central Library in 1999 by the design team of Lluís Clotet and Ignacio Paricio. The massive, 3-foot-thick walls, perforated and crowned with tall brick arches, are striking; the trompe-l'oeil connecting corridor between the reading rooms is a brilliant touch. Even in humble Barceloneta, there are opportunities for really gifted architects to take a historical property in hand and work magic.

Once the arsenal for the Ciutadella—as evidenced by the thickness of the building's walls—this is the only surviving remnant of Felipe V's fortress. For a time it housed the city's museum of modern art, before it was repurposed to house the unicameral Catalan Parliament. Under Franco, the Generalitat—the regional government—was suppressed, and the Hall of Deputies was shut fast for 37 years. Book a free 45-minute guided tour (weekdays) of the building via the website at least two days in advance; it includes the grand "Salon Rose," which is worth a visit in itself.

Reached by walking down Passeig Joan de Borbó and turning left at Plaça del Mar, the adjacent beaches of Barceloneta and Sant Miquel are the easiest to get to and hence the busiest—though they're also the most fun for people-watching. Note that itinerant beach vendors can be a nuisance, and pickpocketing has become increasingly problematic in recent years. The calm waters are easy for swimming, and there are several companies that provide surfing and paddleboard rentals and lessons. Take note of Rebecca Horn's contemporary sculpture of towering, rusting cubes, L'Estel Ferit, a popular meeting spot on Sant Miquel beach. Amenities: food and drink; lifeguards; showers; toilets; water sports. Best for: partiers; surfing (mostly in winter); swimming; walking.

Closest to the Poblenou metro stop, this open-minded, everyone's-welcome beach is a thriving gay enclave and has the city's only designated nudist section, tucked behind the dune. The water-sports center Base Nàutica de la Mar Bella rents equipment for sailing, surfing, and windsurfing; at street level, you'll find a very popular skate park. Outfitted with showers, drinking fountains, and a children's play area, La Mar Bella also has lifeguards who warn against swimming near the breakwater. Amenities: food and drink; lifeguards; showers; toilets; water sports. Best for: partiers; nudists; swimming; windsurfing.

One of Barcelona's most popular beaches for sports lovers, aficionados of volleyball (as well as its foot-based equivalent, footvolley) assemble nets, year-round, to play social tournaments that make great from-your-towel viewing. The wide beach sits just east of the newly rebooted Port Olímpic, and directly opposite the neighborhood built as the residential Olympic Village for Barcelona's 1992 Olympic Games. Vendors sometimes prowl about, offering everything from cold drinks to massages, albeit less intensely than at Barceloneta. Pickpocketing has been an issue here, too, so keep an eye on your belongings. Amenities: food and drink; lifeguards; showers; toilets; water sports. Best for: swimming; walking.

Barceloneta's most southwestern platja (at the very end of Passeig Joan de Borbó), Sant Sebastià is the oldest of the city beaches; it was here that 19th-century locals cavorted in bloomers. In contrast, Ricardo Bofill’s metallic, sail-shape W hotel now stands at the end of a promenade lined with outdoor gyms (frequented by the buff and the beautiful) and populated by sun-ripened skaters and joggers. In 2022, the walkway was extended further around the W hotel: steps lead up to a viewing deck with a panoramic perspective over the city and the sea. Amenities: food and drink; lifeguards; showers; toilets. Best for: partiers; swimming; walking.

The Olympic Port is 2 km (1 mile) up the beach from Barceloneta and is marked by the mammoth shimmering goldfish sculpture by starchitect Frank Gehry, with the towering five-star Hotel Arts just behind. The area has recently undergone a similar-scale overhaul to that witnessed before the 1992 Olympic Games, timed to greet the docking of the prestigious America’s Cup regatta in August 2024. Piers and promenades have been reimagined and expanded to serve as community meeting points for locals and nautically minded visitors, with sailing facilities on offer for anyone with sea legs, while the glut of seedy bars that once lined the Moll de Mestral is now a business hub. Expect smart dining options that also satiate a hunger for sea views.
