Miramare Castle is a 19th-century castle direct on the Gulf of Trieste between Barcola and Grignano in Trieste, northeastern Italy. It was built from 1856 to 1860 for Austrian Archduke Ferdinand Maximilian and his wife, Charlotte of Belgium, later Emperor Maximilian I of Mexico and Empress Carlota of Mexico, based on a design by Carl Junker. The castle’s grounds include an extensive cliff and seashore park of 22 hectares (54 acres) designed by the archduke. The grounds were completely re-landscaped to feature numerous tropical species of trees and plants.
