Beckwith Park is one of the arenas included with the original release of Rocket League. There are 3 variants of Beckwith Park: Normal, Stormy and Midnight, all of which were included with the original release. The arena is named after Ben Beckwith, Lead Level Designer at Psyonix. Beckwith Park is the only map available in custom training.
Beckwith Park is one of the standard maps and is thus frequently used in tournaments. It featured in the RLC Pro League semifinal and twice in the RLCS Season 1 final. It was not included in the RLCS Season 2 map pool.
