In this article, we’re unveiling 8 of Barcelona’s best-kept secrets—perfect for seasoned visitors or residents eager to uncover the city’s lesser-known treasures.

From hidden gems to local quirks, get ready to explore Barcelona like never before and discover the surprising facets that make this city so enchanting.

1. Barcelona’s Bomb shelters

During the Spanish Civil War, Barcelona was subjected to repeated bombings and attacks, with over 1,400 bomb shelters constructed to protect its citizens.

One of the best preserved of these shelters is that of Plaça del Diamant in Gràcia, featuring around 250 metres of tunnels with space for around 200 people, which was rediscovered in 1992. There’s also the huge Refugio 307 in Poble Sec, with capacity for around 2,000 people.

2. Laberint d’Horta

Passeig dels Castanyers, 1, 08035 

One of Barcelona’s oldest gardens is in the neighborhood of Horta Guinardó. Entry is free every day from 10am to 8pm and we recommend visiting in autumn or spring to get lost among the maze and enjoy the pleasant climates these seasons bring.

A perfect magical spot for a stroll, a picnic or an Instagram photo shoot. For more beautiful lush green spots in Barcelona to get a breath of fresh air, read our article with a list of some of the best parks in Barcelona.

3.  Cementeri de Poblenou

Av. d’Icària, 204, 08005 Barcelona

Some of Barcelona’s best-kept secrets can be found in this fascinating cemetery, which dates back to 1819. This peaceful spot is brimming with stunning statues and marble monuments. There’s a guided route at the entrance to make sure you don’t miss the graves of some of the city’s most important figures of the 19th century.

There’s also the impressive Petó de la mort (Kiss of death) by Jaume Barba in which a skeleton with wings leans over to kiss a young man on the cheek.

4. La Biblioteca Arús

Passeig de Sant Joan, 26,

Did you know there’s a Sherlock Holmes collection in Barcelona? The Arús Library is one of Barcelona’s best-kept literary secrets. This magical library looks like something straight out of Harry Potter and is one of the hidden spots in the Eixample district.

With walls lined with books floor to ceiling, it’s the perfect place for book lovers to get lost and browse for hours. Check out the official website for the opening times, guided tours and activities.

5. The unicorns of the Catedral de Barcelona

Pla de la Seu, s/n, 08002

We’re sure you’ve visited Barcelona’s stunning cathedral, and some of you may have even spotted its gargoyles, but did you know there are also unicorns on its façade? If you’re taking a stroll through Barcelona’s Gothic quarter on your trip, be sure to look up when you reach the cathedral.

They say unicorns are symbols of power. If you look closely you may even spot some other animals on its façade from cows and dogs to elephants!

6. Trajano Columns

Carrer de Paradís 10

Seeing as you’re in the area, we have another secret to tell you. Drop into the Centre Excursionista de Catalunya in the Gothic quarter and you’re in for a fantastic surprise. This was once the highest place in the city and here you’ll find the ruins of what was the Temple d’August.

Unfortunately today only 4 columns remain from this temple that dates back to 1 BC, of which there were originally 66! If this is your kind of thing, check out our article with a list of Roman Ruins you can visit in Barcelona. 

7. Jardins de la Tamarita

Passeig de Sant Gervasi, 47, 08022

These gardens are tucked away in the neighborhood of Sarrià-Sant Gervasi. Here you can enjoy almost two hectares of open green space – with centuries-old towering oak trees, stone fountains, hidden pathways, and all types of exotic plants – in what once were the private gardens of the Craywinckel family.

8. Bobby’s Free

C/ de Pau Claris, 85, 08010

Because a list of secret places in Barcelona wouldn’t be complete without a secret bar. From the street Bobby’s Free may look like a barbershop, but actually this clandestine space is a 1920-s themed cocktail bar. Indulge in its speakeasy feel and order a signature cocktail or one of the best gin tonics in town.

As we’ve explored, Barcelona is filled with hidden gems that go beyond the usual tourist spots. From the serene beauty of Cementeri de Poblenou to the ancient Trajano Columns and the peaceful Jardins de la Tamarita, these unique locations offer a fresh perspective on this dynamic city. Whether you’re a seasoned visitor or a local, these secrets invite you to delve deeper into Barcelona’s rich history and vibrant culture. So next time you’re in the city, step off the beaten path and discover the surprises that await around every corner.
