Highest altitude tennis court

The highest tennis court was installed on the circular helipad of the Burj Al Arab luxury hotel in Dubai, United Arab Emirates, on 22 February 2005, at 211 m (650 ft) above the ground and protected only by a simple safety net. Professionals Roger Federer and Andre Agassi played a friendly game – very carefully! – to promote the ATP’s Dubai Duty Free Men’s Open.
