The lungs of London. A monumental stretch of verdant might in the heart of the capital, Hyde Park opened to the public in 1637 and hasn’t looked back since. The park is famous for being the setting of many protests throughout history, although major concerts have replaced rebellions as the main bringer of crowds in the 21st century. Do keep an eye out around Speakers’ Corner though — you never know who you might see on the public soapbox.
