The station has been renovated and enlarged on several occasions. In 1888, the building was partially destroyed by a fire, and between 1985 and 1992, the station was enlarged four times its original size.
After the renewal project, the station was divided into three: Madrid-Puerta de Atocha, Madrid-Atocha Cercanías and Atocha Renfe (metro station). Atocha Cercanías and Atocha Renfe form a large transport interchange that connects various means of public transport.
Atocha’s covered tropical garden is located in the old part of the train station, which was transformed into a foyer in 1992. The garden has over 500 different species of animals and plants. Although, the most popular inhabitants of the garden are the little turtles.
On the morning of 11 March 2004, four commuter trains exploded in Atocha killing 191 people and injuring 1,800. It was the worst terrorist attack in Spain and Europe.
The 11 March 2007, a memorial dedicated to all the victims was inaugurated just outside one of the entrances to Atocha.
