José Miguel Agrelot Coliseum

The Coliseum was a project started during the administration of Governor Rafael Hernández Colón, initially as part of a bid to host the 2004 Olympic Games. The facility was supposed to be constructed between the Roberto Clemente Coliseum and Hiram Bithorn Stadium, about a mile and a half away from the current arena site. The Coliseum would have been used for events such as Gymnastics and Olympic Basketball had the games been held in San Juan.

In 1997, however, Athens was selected to host the games, and the construction of the Coliseum was jeopardized. Recognizing the need for such a facility anyway, the government decided to continue the construction, this time at a site physically close to San Juan's financial district, the Golden Mile. Since the new site was adjacent to a future Tren Urbano station, the Coliseum's planners decided not to incorporate parking facilities to the arena, as to induce visitors to use mass transportation to reach it.

Political opponents of Pedro Rosselló's administration raised various objections to the original plan, claiming that the lot of land purchased for the construction would benefit some of his political party's (PNP) heaviest financial contributors. They also objected to the lack of parking space, claiming that nearby private parking operators, supposedly also money donors to Rosselló's party, would extort high parking fees from people who could not or would not use public transportation to the venue. At the time, the Tren Urbano was in its initial stages of construction; by the time the facility opened it was still under construction. Objectors would also point out that a private operator would take control of the facility under contract from the government of Puerto Rico under what was perceived as a highly expensive contract. The Rosselló administration countered by stating that previous experience with public sports facilities in Puerto Rico, which would quickly fall into disrepair at an accelerated rate requiring constant remodeling, demanded that a private entity should manage the facility. The contract's expense would be justified by bringing in an operating partner with international experience managing world-class facilities, whose reputation would ensure that performers and sport events that had never been staged in Puerto Rico could visit the island.

The Coliseum's construction was stopped for close to two years during the administration of governor Sila María Calderón, the leader of the opposition party (PPD) whose administration followed Rosselló's. She claimed that the Puerto Rican government had spent $242 million for a facility where only 42% of its scheduled project plan had been completed when she took office. The planners and constructors had overlooked the fact that a water pumping station next to the facility had been built over unstable land, and a portion of the building's foundations would have had to be redone because of this. There was even talk of demolishing what had been built and starting from scratch, which infuriated Rosselló supporters, who dismissed the suggestion as merely an excuse to spend more government money, this time to benefit the PPD's financial backers. Plans for a redesigned interior added during the Calderón administration added fuel to the intense public controversy.

Another controversy came about when Banco Popular's Ticketpop was named the ticketing distributor through an exclusive contract, almost ignoring the bid by competitor TicketCenter; Ticketpop would remain the ticketing distributor until August 28, 2019 when rising competitor Ticketera was given the exclusive contract.[4] The original ticket vendor bidding controversy almost went to trial, as both parties argued over who would receive the contract, but the Government of Puerto Rico stood by their original contract with Ticketpop. Local producer Angelo Medina spearheaded a group that wanted the legislature to curb the managing powers of SMG (before merging to ASM Global in 2019), recently-named to oversee operations and activities, because they feared that the company's relationship with non-local television companies would limit the participation of local talent in the arena.

The Coliseum was finally inaugurated on September 4, 2004. The first major show was Van Halen, on September 13, 2004.

The naming of the structure caused a controversy by itself. During the construction phase, plans called for the coliseum to be named simply El Coliseo de Puerto Rico (The Coliseum of Puerto Rico), but when it was also suggested that a private entity could sponsor the facility and thereby lend its name to it, most local politicians objected to the idea, since the financial scandal involving Enron reminded them that the bankrupt company had sponsored a sports facility, which was the Enron Field, later renamed Minute Maid Park in Houston.

Some politicians argued over the naming the Coliseum after a Puerto Rican celebrity. Some of the names mentioned were that of pop star Chayanne, boxer Félix "Tito" Trinidad and actor Raúl Juliá. Puerto Rican law demanded that no facility could be named after a living individual and there were talks of making an exception to the law should a living Puerto Rican icon be honored with the name.

However, the name of beloved local comedian José Miguel Agrelot was chosen when the Coliseum was near its completion. Agrelot himself had suggested the name of Rafael Hernández Marín to be used, and when someone suggested his name instead he was both surprised and concerned.
