Croydon has many places that people enjoy visiting. There are a lot of places of interest such as Croydon Airport, which was the largest airport in London until its closure in September 1959. It was closed because of it was too small to handle the growing number of flights to Croydon so Heathrow and Gatwick took over. It has become a great place for air plane shows and sometimes is hosts along with Biggin Hill. Addington Palace is an 18th-century mansion that was the home of six archbishops.
