This monument was erected with the aim of honoring those who fell in the War of Independence in one of the places where the French troops executed the rebellious population of Madrid. The obelisk was designed by the artist Isidro González Velázquez and was inaugurated in the year 1840, featuring allegorical representations of virtue and patriotism and an inscription that reads "to all those who gave their lives for Spain". Additionally, the ensemble includes an eternal flame as a sign of mourning, and inside it houses the ashes of those executed in Madrid on May 3, 1808, on the Montaña de Príncipe Pío, an event depicted in one of Francisco de Goya's most famous paintings housed in the Prado Museum.
