The architecture of Israel has been influenced by the different styles of architecture brought in by those who have occupied the country over time, sometimes modified to suit the local climate and landscape. Fortified Crusader castles, Islamic madrassas, Byzantine churches, Templer houses, Bauhaus-style modernist buildings, Arab arches and minarets, Russian Orthodox onion domes, and soaring glass-sided skyscrapers - all are part of the architecture of Israel.
