1. Castle Islet (Slotsholmen) is a small island in the heart of Copenhagen, Denmark. The island has a rich history and is home to several important landmarks, including the Danish Parliament, Christiansborg Palace, and the Royal Library. The island was originally home to a fortress built in the 12th century, and over time, many buildings were constructed and destroyed. Today, the island is a popular tourist attraction, offering visitors a glimpse into Denmark’s rich history and culture.
2. Working hours and phone numbers may vary depending on the attraction you want to visit on the island. Christiansborg Palace, for example, is open to the public daily (except on Mondays) from 10 am to 5 pm. The Royal Library has different opening hours, and currently, pre-booking is required due to COVID-19 restrictions.
It is recommended to check the opening hours of the attraction you want to visit in advance.
