What to Wear in Italy in Summer Weather: Summer in Italy is insanely hot; temperatures can reach 35°C or higher. In some cities in the north, such as Milan and Venice, it can be extremely stuffy due to the humidity. The south is hot but it’s better ventilated, so it’s more enjoyable. Be careful to protect yourself during the hottest hours of the day by wearing suncream and a sun hat.
The Colosseum: By the 20th century, a combination of weather, natural disasters, neglect and vandalism had destroyed nearly two-thirds of the original Colosseum, including all of the arena’s marble seats and its decorative elements. Restoration efforts began in the 1990s, and have proceeded over the years, as the Colosseum continues to be a leading attraction for tourists from all over the world.
