Abelardo Sánchez Park is the largest urban green space in the Spanish city of Albacete, and the third oldest (after the Jardinillos Park and La Fiesta del Árbol), which makes it the city's "Park" par excellence. Located right in the centre of the capital, it is the largest urban park in Castilla-La Mancha. It is one of the most significant places in La Mancha.6

During the plenary session of the Albacete City Council on 23 August 1910, it was decided to build a large park in the south of the city, and construction work began on 23 February of the following year. The construction work involved the planting of 12,000 pine trees and 400 other trees of different species, at a total cost of 31,788.68 pesetas of the time. The mayor at that time was Abelardo Sánchez. At first it was called "Parque de Canalejas" in homage to José Canalejas, President of the Spanish Government, who was assassinated by an anarchist in 1912.

During the Franco regime it was renamed "Parque de los Mártires" until the arrival of democracy it was given its current name "Parque Abelardo Sánchez" in honour of the mayor who promoted its construction.

Between 1968 and 1978 the Museum of Albacete was built on the former Swan Pond.

On 17 November 2002, the Abelardo Sánchez Park was reopened after a controversial refurbishment that lasted eleven months (during which the park was closed) in which numerous improvements were made, but also 378 pine trees were cut down. During this remodelling, the monument to the Fallen (dated after 1940) was also moved to the Albacete Cemetery.
