Quinta da Regaleira in Sintra is a historic estate where an early twentieth-century palace rises above gardens threaded with tunnels and the celebrated Initiation Well. Set on the hillside just outside Sintra’s historic centre, it forms part of the Cultural Landscape of Sintra recognised by UNESCO and brings together architecture, grottoes and subterranean passages in a single ensemble.
Palace, estate and the Monteiro Millionaire
