SI-Centrum, Shopping and entertainment complex in Möhringen, Germany.

SI-Centrum is an entertainment complex in Möhringen, south Stuttgart, built around the Hotel Stuttgart International that has stood on the site since 1960. Its landmark is a tall hotel tower clad in vertical grey and blue glass strips, with "MILLENNIUM HOTEL" running down a light-grey corner band. Around it stand the Stage Apollo Theater (1,838 seats) and Stage Palladium Theater (1,807 seats), linked underground, plus lower white wings housing restaurants, bars, a CinemaxX cinema and the SchwabenQuellen spa.

The site has held the Hotel Stuttgart International since 1960, and the complex took its name from it. In the early 1990s the Stella AG, led by Rolf Deyhle, built an Urban Entertainment Center around the hotel, opening it in 1994. An extension with a second musical hall followed in 1997. Stella went insolvent in 1999, and Stage Entertainment took over most shares in 2002.

The two musical theatres opened in December 1994 and December 1997. The Apollo seats 1,838 people on three levels, the Palladium 1,807; both are run by Stage Entertainment, which took over most of Stella AG's shares in April 2002. The name SI comes from the Hotel Stuttgart International, which has stood on the site since 1960.

The SI-Centrum lies on the B 27 between Degerloch and Echterdingen. From Stuttgart Hauptbahnhof take tram lines U5, U6 or U12 to Möhringen Bahnhof, then U3 toward Plieningen to Salzäcker; alternatively S1, S2 or S3 to Vaihingen station and U3 from there. By car, leave the A 8 at Stuttgart-Degerloch/Möhringen.

The hotel tower in the complex carried the name Millennium Hotel & Resort Stuttgart from 1997 until it was renamed Dormero Hotel Stuttgart on 1 September 2011, following renovation work completed in July 2012. The site's name comes from the Hotel Stuttgart International, which has stood here since 1960.
