Le Grand T, Entertainment centre in Nantes, France.

Le Grand T is a theatre in Nantes at 84 rue du Général-Buat, built in 1982-1983 as Espace 44 to plans by architect Claude Jeffroy and scenographer Igor Hilbert. Its main hall seats 849, and a chapel annexe holds 99 or 107. The whole building covers 2,700 m² and includes a reception hall, restaurant and technical annexes.

The Maison de la culture de Nantes was founded as an association in 1970, led by Jacques Vitaly until 1975, then by Jacques Couturier and Loïc Vollard until 1978. Dissolved in June 1981, it was rebuilt in March 1982 on the initiative of the Loire-Atlantique department, which alone funded it. The building opened as Espace 44 in 1982-1983, designed by architect Claude Jeffroy with scenographer Igor Hilbert, and was extended and restored in 1997. On 1 January 2014 it became the public establishment Le Grand T, théâtre de Loire-Atlantique.

The venue's name comes from its address on rue du Général-Buat, where the letter T stands for théâtre. Its main hall seats 849 and the adjoining chapel 99 or 107, so the same building hosts both large productions and small-format shows. The chapel is a former religious space kept as a second stage.

The venue provides technical support and full equipment for all types of performing arts productions. Visitors should check ahead to see what shows are currently scheduled, as programming changes throughout the year.

The building opened in 1982-1983 as Espace 44, designed by architect Claude Jeffroy with scenographer Igor Hilbert of Hilbert & Associés. It covers 2,700 m² and originally held 857 seats, reduced to 849 after the 1997 extension and restoration works. A chapel adjoining the hall seats 99 or 107 spectators.
