Cotai (Chinese: 路氹城; Cantonese Yale: Louhtáhm Sìhng; Portuguese: Cotai) is a 5.2-square-kilometer (2.0 sq mi) piece of reclaimed land on the top of the Seac Pai Bay between Taipa and Coloane islands in Macau[1] that has connected two independent islands since 2005.

In 1968, a causeway (Estrada do Istmo [yue]) connecting Taipa and Coloane was inaugurated.

[citation needed] Galaxy Entertainment Group's Grand Waldo Hotel was the first casino to commence operations in Cotai, opening its doors in May 2006.

[citation needed] The largest property on Cotai so far is Las Vegas Sands' The Venetian Macao, which opened its doors on August 28, 2007.

[5] Melco PBL Holdings opened the City of Dreams directly across the street from the Venetian on June 1, 2009.
