Emperor Maximilian Memorial Chapel, Memorial chapel at Cerro de las Campanas, Querétaro, Mexico

The Emperor Maximilian Memorial Chapel is a small Roman Catholic chapel on the Cerro de las Campanas, built in an eclectic Viennese style and dedicated on 10 April 1901. Its altar and altarpiece were made at the Querétaro School of Arts and Crafts, and the cross on the altar comes from the Austrian frigate SMS Novara.

The hill was the last stronghold of the Second Mexican Empire. Emperor Maximilian, besieged in Querétaro since March 1867, surrendered here on 15 May 1867 to General Mariano Escobedo. A court-martial sentenced him and generals Miguel Miramón and Tomás Mejía to death; they were executed on 19 June 1867. In 1900 Emperor Franz Joseph I commissioned the chapel, designed by Maximiliano Mitzel and dedicated on 10 April 1901.

The chapel was commissioned by Emperor Franz Joseph I of Austria-Hungary for his brother Maximilian, and its altar cross comes from the SMS Novara, the frigate that carried Maximilian to Mexico and later his remains back to Austria. Maximilian is buried in Vienna's Imperial Crypt, so this site is a memorial rather than a tomb.

The chapel sits within Cerro de las Campanas National Park and opens daily to visitors, with parking available nearby. Information panels at the site explain the history and meaning of this memorial location.

The cross on the altar comes from the Austrian frigate SMS Novara, the ship that carried Maximilian and Carlota to Mexico and later took his remains back to Austria. The 1886 monument, three stone columns engraved with the names of the dead, was commissioned by Governor Rafael Olvera.
