The result of the collaboration between the city of Ostrava, Silesian Ostrava Castle, Dolní Vítkovice, and Landek Park is the creation of an exclusive product called 4 Ticket. The ticket allows entry to the 4 most interesting attractions in Ostrava. Interested visitors can start their imaginary tourist route by visiting Landek Park in Ostrava Petřkovice. The area, which includes the national natural monument of Landek Hill, a network of cycling paths, a campsite, and the largest Mining Museum in the country, offers experiences that are hard to forget. Authentic descent into the mine with guides, former miners, reveals everything interesting about coal mining and the history of mining rescue services. Another stop could be the Viewing Tower of the New Town Hall, offering a unique view of Ostrava, accompanied by a historical commentary. This will reveal interesting facts about Ostrava and the town hall itself. Although it may seem so, the tour of the viewing tower is not physically demanding, it is accessible without barriers, making it suitable for all age groups. Continue to Silesian Ostrava Castle. It will offer a tour of the castle grounds, including a visit to the new Museum of the Amber Road and the Silk Road. The courtyard and some areas of the castle are barrier-free, but the castle tower with the museum exhibition has a steep staircase that is not suitable for people with reduced mobility. The estimated time for the tour is 1 hour, and visitors will learn not only about the history of the castle but also why the castle has sunk by a full 16 meters. The unique, more than twenty-meter extension of the historical blast furnace was designed by the renowned architect Josef Pleskot and represents one of the prominent landmarks of Ostrava. It rises to a height of nearly 80 meters and was inaugurated by the famous athlete Usain Bolt. The extension is also in the shape of a helix, hence the name Bolt Tower. Bolt Tower is another place that is definitely worth visiting. The guided tour captivates with the unique history of Dolní Vítkovice, the production of pig iron, coal mining, and the furnace itself. An alternative for families with children is a visit to the Great World of Technology in the Dolní Vítkovice area. This popular family science centre offers 14,000 square meters of interactive fun. The Great World of Technology educates all age groups in an entertaining way. Visitors will find 4 permanent exhibitions and one temporary exhibition here. The validity of the ticket is 6 months from the date of purchase and can be used continuously over the course of half a year. It will be offered at the receptions of all mentioned attractions either for 509 CZK for individuals or 1599 CZK as a family ticket.
