In fact, there are many introductions to the attractions of the three ancient castles, which are also explained in the travel notes of major travel websites. I will list the attractions introduction from the official website of the Nordic Tourism Bureau. It is relatively complete. I hope it can be helpful. you! ~ Kronborg Palace is located on the coastline of Oresund and is the most important castle in the Nordic Renaissance. It is world-famous because Shakespeare's famous play "Hamlet" uses the castle as the background; it is the most famous castle in Denmark, with about 200,000 tourists from Denmark and all over the world visiting it every year. Frederick II's Kronborg Palace was both an elegant Renaissance castle and a massive military fortress, surrounded by major fortifications such as bastions and fortresses. Some of the historic rooms display Renaissance and Baroque decorations, and the most important attractions include the 62-meter-long ballroom, the well-preserved chapel, and the statue of "Holger the Dane". Frederikborg Castle Frederikborg Castle is located in the center of Hillerod, spanning three islands in the lake. The oldest part of the castle was built in 1560 by King Frederik II, after whom the castle is named. Most of the existing castle was built between 1600 and 1620 by Christian IV, son of Frederick II. This building embodies the Dutch Renaissance style, with extensive pediments, sandstone decorations, copper roofs and spires. The castle burned down in 1859 and was rebuilt between 1860 and 1884 with funding from the brewer J. C. Jacobsen and the Carlsberg Foundation. After reconstruction, Frederiks Castle became the National Museum of Danish History. Egeskov Castle For more than 450 years, Egeskov Castle has stood majestically on the beautiful southern island of Funen. The name Iesco originally came from a building of the same name. Today, Iesco is the best preserved moated castle in Europe. Follow the tour guide to visit the first and second floors of the castle, and you can carefully observe the exquisite interior decoration of Iesco Castle. You will also find chronological information on all the owners of Iesco, as well as other key information that provides insight into the details of the castle, such as the approximately 2,000 windows with decorative glass. The most unique "Titania Palace" can be seen on the first floor, which is another important reason why you must visit and experience the Iesco Castle in person.
