Metropolitan Cathedral of Christ the King

Known colloquially as Paddy's Wigwam, Liverpool's Catholic cathedral is a mightily impressive modern building that looks like a soaring concrete teepee, hence its nickname. It was completed in 1967 according to the design of Sir Frederick Gibberd after the original plans by Sir Edwin Lutyens, whose crypt is inside. The central tower frames the world's largest stained-glass window, created by John Piper and Patrick Reyntiens.
