Located in the time machine that is the Barrio de las Letras, the Ateneo de Madrid is the most important private cultural institution in Spain’s contemporary history. A home for culture whose origins date back to the early 19th century and whose legacy we can enjoy in every corner today.

Its famous Portrait Gallery, the Main Chair, its enormous library… rooms that remain as vibrant as ever thanks to the many events held behind its doors, from exhibitions to candlelight concerts and lectures.

A bit of history about the Ateneo de Madrid

We recommend candy and popcorn because its story is worthy of a screenplay: with the aim of spreading culture and educating the public, the Spanish Ateneo was founded in 1820. But the arrival of absolutism three years later led Ferdinand VII to shut it down, forcing its founders into exile. It wasn’t until 1835 that, following the monarch’s death and under the protection of Queen Regent María Cristina, the exiles returned and the institution reopened its doors. And in what style.

During the 19th and 20th centuries, the Ateneo became the place where politicians, scientists, and writers such as Machado, Unamuno, and Manuel Azaña gathered. A home for freedom of expression that lost its independence and was heavily censored during the Civil War and the dictatorship. Until the Transition, when it regained an essence that we can still enjoy today.

Things to do at the Ateneo de Madrid

The Ateneo de Madrid’s cultural calendar honors its history with a wide-ranging program of events, always updated on its official website. Book presentations and literary lectures are a constant at the Ateneo, as are exhibitions and debates on political, social, or scientific topics.

But what really stands out among all its events are the concerts. Classical and chamber music recitals are one of its hallmarks, but since the Ateneo became the new home of the iconic Café Central, live jazz sessions have become increasingly frequent. Also noteworthy are the famous Candlelight concerts, with many dates at the Ateneo featuring both classical and contemporary tributes.

Facts, trivia, and interesting details about the Ateneo de Madrid

1. It houses valuable Neo-Greek and Modernist paintings

That’s right—specifically, in its Assembly Hall, decorated with these Modernist paintings that are an undeniable gem. As for the Neo-Greek style paintings, they are the work of Arturo Mélida and can be found in the beautiful Assembly Hall and English Hall.

2. Its long list of illustrious members includes names such as Clarín and Galdós

3. It boasts the second-largest library in Spain

Indeed. The Ateneo de Madrid library is the second-largest library in Spain, second only to the National Library. A wonderful space that, founded the same year as the institution, currently houses 350,000 volumes and four reading rooms with 300 desks for members.

4. She launched a campaign to ensure that women members of the Ateneo took their rightful place in the Portrait Gallery

Of the 188 portraits that were distributed throughout the Portrait Gallery, only one featured a woman. The portrait of Emilia Pardo Bazán was the only one until 2021, when the initiative “Women in Their Rightful Place” was launched, aiming to include all those illustrious women of the Ateneo who contributed to Spanish culture and politics.

A move as well-deserved as it is necessary, which has already incorporated the faces of women such as Carmen Laforet, Clara Campoamor, and Almudena Grandes. And counting.
