Sovereign city-state of 0.49 km² on the west bank of the Tiber, established in its current form by the Lateran Treaty of February 11, 1929. St Peter's Basilica, completed 1626, occupies the traditional burial site of the apostle Peter; the dome (Michelangelo and Giacomo della Porta, 1590) rises 136.6 metres and remains the tallest dome in the world. The basilica's interior length is 218.7 metres; the floor of the nave is engraved with the lengths of the world's twelve next-largest churches for direct comparison. The Vatican Obelisk in St Peter's Square is a 25.5-metre red granite monolith brought from Heliopolis to Rome by Caligula in 37 CE and re-erected by Domenico Fontana in 1586 in a feat of engineering that required 900 workers and 140 horses.
The smallest country on Earth holds an Egyptian sun-pillar that predates Christianity by 1,900 years.
