On 17 March 1908, the Garden-hall Passos Manuel was inaugurated. Architect Mário de Abreu designed the interior and made alterations to the principal hall, staircase and the tower facade, which was covered in windows, and removed the original neon green, red and white that accompanied the original structure at the time of its opening. The Garden-hall Passos Manuel was the first local public hall in the city and "was the point of encounter for Portuense society, an elegant local, with sophisticated decorations, with ample gardens and luminous fountains that proportioned all types of entertainment. It had the capacity for 700 people ". In 1911, the hall was renovated, which included a garden and esplanade, party hall, pavilion restaurant, hall and small theatre. By 1937, though, there were already rumblings that demand exceeded the capacity of the structure; the first plans to construct a grand, modern events hall were developed by architect José Porto. In 1938, the Garden-hall Passos Manuel was deactivated and demolished. The following year, Cassiano Branco assumed the position of principal architect for a new project, with the assistance of Júlio de Brito. The construction of the coliseum was a troubled process, that risked the careers of various architects, such as José Porto, such as Dutch architect, Yan Wills and Júlio de Brito. But, since he was connect to the Companhia de Seguros Garantia, proprietor of the Garden-hall Passos Manuel, Brito continued to be connected with the project. Charles Ciclis, who authored various projects in Parisian theatres, was invited by Cassiano Branco to work on the Coliseum project. Of his interior designs, apparently only the candelabras and doors, were included in the designs, although the designer was never remunerated. The new building opened on 19 December 1941. With changing tastes and advent of popular cinema, the old concert hall was transformed into a cinema/studio in 1971. By 1981, there was a proposal to classify the building, during the 2nd Congress of the Association of Portuguese Architects. But, the first initiatives were open on 11 December 1987, by the IPPC, supported by the 18 December dispatch by the Vice-President. In 1995, the Empresa Artística, SA/Grupo Aliança-UAP, sold the coliseum to IURD, the Brazilian Universal Church of the Kingdom of God. This news boosted an unprecedented movement of indignation and revolt on the part of the Portuenses. Various artist and institutions such as the municipal council, civil governor and public, reacted unanimously against the announced end of the coliseum. This move resulted in the establishment of the Associação "Amigos do Coliseu do Porto", who helped stop its sale and protect the building. On 28 September 1996, a public deed for the purchase of the coliseum by the municipal council, which included the cinema Passos Manuel, the Garden-hall, attic hall and a lithography for 680,000 contos. During an event, a fire started in the coliseum that completely destroyed the stage, principal hall and dressing rooms. The recuperated building was reopened on 17 December 1996. On 10 September 1998, the Vice-President of IPPAR at the time, re-confirmed the IPPAR's 1987 intent to classify the building. This process had advanced little in the intermittent years, so that by 12 September 2005, there was a proposal by the DRPorto to classify the building as an Imóvel de Interesse Público. This was later included in the far larger special protection zone that included the buildings of the public works department, Chapel of Almas, Café Majestic, Church of Saint Ildefonso and Cinema Batalha, which was later approved by the consultive council of IGESPAR, and supported on 29 September 2010, by the National Council of Culture. The Secretary of State for Culture ratified its classification as a Property of Public Interest. In September 2015, a professional ballet troop became the resident company at the Coliseu, the Balleteatro. Between 1997 and 2001, there systematic changes to the buildings interiors, that included the substitution of the electrical systems, the construction of new washrooms on all floors, the substitution of water supply, security and fire protection systems, the repair of the roof, recuperation of the dressing rooms on five floors and the elaboration of a new aesthetic with the building. Moving and scenic lighting equipment were upgraded, the heating network was recovered and improved, an electronic subtitling system and an electronic ticket office were installed. The auditorium was completely rebuilt to improve the acoustics and the visibility of the spectators, while a warehouse was built under the auditorium. A second orchestra pit and a new circus track were installed on a hydraulic lifting plate.
