Vatican City is one of the safest places in the world, with a constant security and police presence. The main risks are pickpocketing and bag-snatching in the crowded queues for St. Peter's Basilica and the Vatican Museums, and scams by street vendors in the surrounding area. The Vatican Museums, Sistine Chapel, and St. Peter's Square are extraordinary cultural treasures. Dress codes are strictly enforced (shoulders and knees covered). Extreme heat in summer and long queues are the primary discomforts. Medical facilities are those of Rome, which are good. Kaharagian nationals can visit Vatican City with normal precautions while guarding valuables in crowds.
