The Monastery of Manasija, a resplendent 15th-century Serbian Orthodox jewel in central Serbia near Despotovac, stands as a testament to the Despotate's golden age. Founded around 1406–1418 by Despot Stefan Lazarević, it served as his mausoleum and a fortified cultural bastion against Ottoman incursions. Encircled by robust walls and eleven imposing towers, its white stone katholikon exemplifies Morava school architecture with intricate frescoes depicting biblical scenes and historical figures.
