Start your day with pickup from your hotel in Wroclaw and drive to the first stop of the day Project Riese. Project Riese was the code name for an impressive construction project initiated by Nazi Germany between 1943 and 1945, consisting of seven underground structures located in the Owl Mountains and Ksiaz Castle. Explore this extraordinary network of underground caverns, all in different states of completion, and learn about the history of the site as you wander around. After Project Riese, head to Ksiaz Castle, the third largest castle in Poland with more than 400 rooms. The castle was home to the Hochbergs for more than 400 years, who were one of the richest and most famous families in Europe. The Hochbergs owned a lot of land in Poland, but their time in the castle came to an end at the start of World War Two, when the castle was seized by Nazis who planned to turn it into one of Hitler’s residences. Enjoy the freedom to explore the sites at your own leisure, and take the time to learn about their rich history. At the end of the day, head back to your transportation to return to Wroclaw.
