The Puerta de San Andrés (Spanish for "Gate of Saint Andrew") is a city gate in Segovia, Castile and León, Spain, forming part of the city's medieval fortifications.

[1] It has two towers, one square and one polygonal, an arch, a gallery of irregular windows, loopholes, cornices, pyramidal battlements and heraldic shields.

[4] By the end of the 19th century, the polygonal wall tower had deteriorated and part of it had collapsed, and it was still in ruins as of 1947.

[6] On 3 June 1931 it was declared a Monumento Histórico-Artístico, through a decree published in the Gaceta de Madrid signed by the President of the Provisional Government of the Second Spanish Republic, Niceto Alcalá-Zamora, and the Minister of Public Instruction and Fine Arts, Marcelino Domingo.
