Roseburg "Roseburg Palace", built in 1606, before 1720 as the royal residence, is one of Denmark's most famous castles. In 1606, King Christian IV of Denmark built a park on the outskirts of Copenhagen, known as the King's Park. Although the view of King's Park was pleasant, but lacked a proper building, Christian IV built the castle in the north-east corner of the park, which was rebuilt and finally completed in 1633. This is the current Roseburg Palace. Rose Fort Palace is more than 400 years old, its red brick walls and green bronze eaves are very eye-catching, several towers clustered together, the spire above the sky, is a typical Renaissance style, surrounded by moats. In 1634, it became the emperor's summer palace. After 1883, it became a treasure trove of kings. The king's garden was very large, facing the castle was a main road, two rows of tall trees stood there like sentinels, and on both sides of the road were wide leisure grounds, green grass and lush trees. Not far away, there will be fountains, sculptures, leisure seats, etc. The most amazing part of the King's Garden is the botanical garden in the corner of the park. All kinds of flowers here are colorful. Red, pink, purple, yellow, colorful. There are also green plants trimmed into various shapes, with paths in the middle. We walked through the botanical garden, bathed in sunshine, breeze, and flowers overflowing.
