The Crowne Plaza Muscat hotel at Oman Convention and Exhibition Centre (OCEC), worth $96m (OMR37m), was inaugurated by Omran, Oman’s tourism development company.
Crowne Plaza Muscat OCEC comprises 296 rooms, in addition to meeting, event, and food and beverage (F&B) facilities.
Omran's sustainability policies were said to have supported the hotel's design in line with LEED Gold standards.
Peter Walichnowski, the chief executive officer of Omran, said the government agency had "witnessed great success" since the opening of OCEC's exhibition halls in October 2016.
He added: "Developed to align with Oman’s vision to strengthen and diversify the national economy, the OCEC project aims to accelerate the capacity, scope, and potential of the tourism sector in the sultanate.
"We have more than 50 global and regional events scheduled, and it is with great pride that we can now offer accommodation at the Crowne Plaza Muscat OCEC."
The four-star hotel is the first of three to open within OCEC, which forms the first phase of Madinat Al Irfan district.
A five-star, JW Marriott-branded hotel, and the OCEC Convention Centre facility, are due to open in the district next year.
Upon completion, the precinct will also include a business park, retail areas, and residential districts.
