Built as a grand residence for the Duke of Courland, this magnificent palace is a monument to 18th-century aristocratic ostentatiousness, and rural Latvia's architectural highlight. It was designed by Italian baroque genius Bartolomeo Rastrelli, who is best known for the Winter Palace in St Petersburg. About 40 of the palace's 138 rooms are open to visitors, as are the wonderful formal gardens, inspired by those at Versailles.
