The Battle of Kratzau occurred on 11 November 1428 between an Imperial Silesian army and the Sirotci Hussites in Kratzau, Bohemia. During the battle, the Imperial Silesian army under Hans von Polenz overpowered the Hussite troops. In November 1428, the Hussites under the leadership of Jan Královec launched a campaign from the occupied Kratzau of Friedland and Ostritz to Löbau. The city was not taken by the Hussites, and so they retreated back to Kratzau. Silesian and Lusatia troops pursued the Hussites, defeating them near Kratzau. The loss of vehicles with rations was essential for the Hussites, since supplies were intended for units besieging the Lichnice Castle.

Ještěd (Czech pronunciation: [ˈjɛʃcɛt]; German: Jeschken) is the highest mountain of the Ještěd–Kozákov Ridge in the north of the Czech Republic, at 1,012 m (3,320 ft). It is the symbol of the city of Liberec. On the summit is the Ještěd Tower restaurant, hotel and television tower, designed by Karel Hubáček, accessible by road or cable car (Ještěd cable car). The mountain also has a ski resort. From the summit there are views to Germany and Poland.

Ještěd Tower is a television transmitter on the top of Mount Ještěd near Liberec in the Czech Republic. It is 94 m (308 ft) high. It is made of reinforced concrete shaped in a hyperboloid form. The tower's architect is Karel Hubáček who was assisted by Zdeněk Patrman, involved in building statics, and by Otakar Binar, who designed the interior furnishing. It took the team three years to finalize the structure design (1963–1966). The construction itself took seven years to finish (1966–1973).The hyperboloid shape was chosen since it naturally extends the silhouette of the hill and, moreover, well resists the extreme climate conditions on the summit of Mount Ještěd. The design combines the operation of a mountain-top hotel and a television transmitter. The hotel and the restaurant are located in the lowest sections of the tower. Before the construction of the current hotel, two huts stood near the mountain summit: one was built in the middle of the 19th century and the other was added in the early 20th century. Both buildings had a wooden structure and both burned to the ground in the 1960s. The tower is one of the dominant features of the North Bohemian landscape. The gallery on the ground floor and the restaurant on the first floor offers views as far as to Poland and Germany. The tower has been on the list of the Czech cultural monuments since 1998, becoming a national cultural monument in 2006. In 2007 it was entered on the Tentative List of UNESCO World Heritage sites. In 1969 Karel Hubáček was awarded the prestigious Perret Prize of the International Union of Architects (UIA).
