Wolf's Lair (Wolfsschanze) was Adolf Hitler's first Eastern Front military headquarters in World War II. The complex, which would become one of several Führer Headquarters located in various parts of occupied Europe, was built for the start of Operation Barbarossa - the invasion of the Soviet Union - in 1941. It was constructed by Organisation Todt.
The top secret, high security site was in the Masurian woods about 8 km from the small East Prussian town of Rastenburg (now Kętrzyn). Three security zones surrounded the central complex where the Führer's bunker was located. These were guarded by personnel from the SS Reichssicherheitsdienst and the Wehrmacht's armoured Führer Begleit Brigade. Despite the security, an assassination attempt against Hitler was made at Wolf's Lair on 20 July 1944.
Hitler first arrived at the headquarters on 23 June 1941. In total, he spent more than 800 days at the Wolfsschanze during a 3½-year period until his final departure on 20 November 1944. In the summer of 1944, work began to enlarge and reinforce many of the Wolf's Lair original buildings, however the work was never completed because of the rapid advance of the Red Army during the Baltic Offensive in autumn 1944. On 25 January 1945, the complex was blown up and abandoned 48 hours before the arrival of Soviet forces. The Red Army captured the abandoned remains of the Wolfsschanze on 27 January without firing a shot. It took until 1955 to clear over 54,000 land mines which surrounded the installation. Today only impressive concrete ruins exist.
Tyniec Benedictine abbey was founded by King Casimir the Restorer probably around 1044. Casimir decided to rebuild the newly established Kingdom of Poland, after a Pagan rebellion and a disastrous Czech raid of Duke Bretislaus I (1039). The Benedictines, invited to Tyniec by the King, were tasked with restoring order as well as cementing the position of the State and the Church. First Tyniec Abbot was Aaron, who became the Bishop of Kraków. Since there is no conclusive evidence to support the foundation date as 1040, some historians claim that the abbey was founded by Casimir the Restorer’ son, King Boleslaw II the Generous.
In the second half of the 11th century, a complex of Romanesque buildings was completed, consisting of a basilica and the abbey. In the 14th century, it was destroyed in Tatar and Czech raids, and in the 15th century it was rebuilt in Gothic style. Further remodelings took place in the 17th and 18th centuries, first in Baroque, then in Rococo style. The abbey was partly destroyed in the Swedish invasion of Poland, and soon afterwards was rebuilt, with a new library. Further destruction took place during the Bar Confederation, when Polish rebels turned the abbey into their fortress.
In 1816, Austrian authorities liquidated the abbey, and in 1821-1826, it was the seat of the Bishop of Tyniec, Grzegorz Tomasz Ziegler. The monks, however, did not return to the abbey until 1939, and in 1947, remodelling of the neglected complex was initiated. In 1968, the Church of St. Peter and Paul was once again named the seat of the abbot. The church itself consists of a Gothic presbytery and a Baroque main nave. Several altars were created by an 18th-century Italian sculptor Francesco Placidi. The church also has a late Baroque pulpit by Franciszek Jozef Mangoldt.
