Open all year round, the Debrecen Zoo is home to some 900 individuals of 170 species from all five continents. Besides permanent exhibits, there are a number of daily events and activities involving close visitor encounters with fascinating animals as part of the Animals in Action program, as well as a number of seasonal events such as summertime Evening Walks or Animal Christmas. A full member of the European Association of Zoos and Aquaria (EAZA) since 1994, the Zoo also reflects the current need for the protection of biodiversity by contributing to coordinated conservation efforts like European Endangered Species Programs (EEPs) through managing healthy and productive populations of various endangered species like the leopard cat, the reticulated giraffe, the African penguin, and the ring-tailed lemur.
Integrated into the Zoo and Amusement Park, the ever-growing botanical collection currently features around 650 species, including ones from the Great Forest biotope and other parts of Hungary as well as ones native to various exotic corners of the world. There is also a Scent Garden section, home to a wide variety of aromatic herbs, enabling visitor interaction through the sense of smell. https://www.debrecen.hu/en/tourist/places/nagyerdei-entertainment-complex
The main façade of the Fisherman’s Bastion, running parallel to the Danube, is approximately 140 metres long. The seven stone towers with their pointed tops symbolise the leaders of the Hungarian tribes who conquered the country in 896. It was built in place of the old fortification walls in neo-Romanesque style between 1895 and 1902 on the plans of Frigyes Schulek, who was also in charge of the reconstruction of the Mathias Church. The Bastion takes its name from the guild of fishermen that was responsible for defending this stretch of the city walls in the Middle Ages. https://www.budapest.com/city_guide/sights/monuments_of_art/fishermens_bastion.en.html
The Reformed Great Church of Debrecen is one of the most significant Classicist historic buildings of Hungary. It was designed by Mihály Péchy, and built between 1805 and 1822. Its north-south nave (with the organs at its two ends and with the pulpit at its north end) is 38 m long and 14 m wide; its east-west aisle is 55 m long and 15 m wide. http://www.debrecencity.com/en/debrecen/culture/churches/the_reformed_great_church
Royal Palace – Buda Castle is the historical castle and palace complex of the Hungarian kings in Budapest and was first completed in 1265. The first, Gothic style royal palace was built during the reign of Louis the Great, King Sigismund and King Matthias (from the middle of the 14th century until the end of the 15th). It became a royal residence of European rank, with its Gothic and Renaissance elements. Buda was occupied by the Turks in 1541, and it was only retaken during the Christian siege of Buda in 1686.
In WWII, the palace and the Castle District were the last refuges of the Germany Army, which fell under heavy siege from the invading Soviet Army. The palace was again damaged; reconstruction started in the 1950-s. Leading architects of the age have announced that they wanted to return to the 18th-century Baroque form of the palace, and at the same time keep its 19th-century dimensions. They constructed a Baroque façade that never existed before. This was because 20th-century architects saw no value in an eclectic style, although this is now considered to be the most valuable aspect of Budapest’s buildings. https://bookinbudapest.com/royal-palace-buda-castle
The first citizens arrived to Castle Hill in the 13th century after the Mongolian invasion, seeking protection in the hills of Buda. The first royal castle was built around this time. The golden age of Castle Hill was in the 15th century, following the marriage of King Matthias Corvinus and Beatrix of Naples in 1476. http://visitbudapest.travel/guide/budapest-attractions/buda-castle-hill/
