Agra Fort is a historical fort in the city of Agra in India. It was the main residence of the rulers of Sikarwar clan of rajputs until mughals occupied it and Mughal Dynasty until 1638, when the capital was shifted from Agra to Delhi.

Castel Sant'Elmo is a medieval fortress located on a hilltop near the Certosa di San Martino, overlooking Naples, Italy. The name "Sant'Elmo" derives from a former 10th-century church, Sant'Erasmo, shortened to "Ermo" and, finally altered to "Elmo". It presently serves as a museum, exhibition hall, and offices.
