Gliwice

This is a tower built in 1322 as part of the city walls, plus an armory building. It was probably never a seat of the Piast royal dynasty, whose power was ebbing by that date. It's now a branch of Gliwice Museum.

Completed in 1900 as the Church of Sts Peter and Paul, this was promoted to cathedral in 1992 when Gliwice became a diocese.

A city icon, this 118 metre-high radio mast is the tallest wooden structure in Europe. Erected in 1934, it was the target of the "false flag" attack of 31 Aug 1939, the pretext for Germany to invade Poland. The SS dressed in Polish uniforms, stormed the transmitter and broadcast an anti-German message. Next morning German radio barked that Poland was invading but Seit 5 Uhr 45 wird jetzt zurückgeschossen! - "Since 05:45 we are returning fire!". Two days later Britain and France declared war against Germany. The mast still supports radio and mobile phone transmissions while the building is now part of Gliwice Museum, with old equipment and a film about the attack. Labelling is only in Polish.
