The **Coliseo de Puerto Rico José Miguel Agrelot**, often called the "Choliseo" by locals, is the largest indoor arena in Puerto Rico and the Caribbean, dedicated to entertainment and sports. It officially opened on September 4, 2004, after five years of construction costing approximately $252.6 million, funded by the Puerto Rican government[1][2]. The venue is strategically located in the Hato Rey district of San Juan, adjacent to the Golden Mile financial district and accessible via the Tren Urbano metro system, which launched shortly after the Coliseo[1][2][6]. The Coliseo was originally conceived as part of Puerto Rico's bid to host the 2004 Olympic Games, aiming to build a world-class arena for multiple uses. Although the bid was unsuccessful, the project continued and evolved into a premier venue for concerts, sports, and cultural events[1]. Designed by prominent Puerto Rican architects Alberto E. Ferrer González and Rebecca Riefkohl Biaggi, among others, the arena boasts a seating capacity of up to 18,500, ranking it among the top arenas in the U.S. and Latin America[1][3]. Managed by ASM Global and owned by the Puerto Rico Convention District Authority, the Coliseo has hosted over 600 events and welcomed more than 5 million spectators since its opening, generating around $200 million in ticket revenue by 2013[2]. It has been a landmark venue for major international performances, including the first WWE pay-per-view event held outside the continental U.S., Canada, and the UK in 2005[2]. The arena is also known for record-breaking concerts, such as Daddy Yankee and Don Omar's sold-out shows in 2015[4]. After Hurricane Maria in 2017, the Coliseo temporarily served as a distribution center for relief supplies before resuming events in March 2018[2]. Its modern architecture
