A-level indoor tourist attractions in Shanghai which have reopened gradually from March were ordered on Sunday to close again until further notice from Monday to prevent the spread of the coronavirus, their operators said.

These include the Oriental Pearl TV Tower, Shanghai Tower and Madame Tussauds, along with Huangpu river cruises.

Shanghai Tower will close its observatory again from Monday, it said Sunday.

Twisting 632 meters above Lujiazui in Pudong, Shanghai Tower is the world’s second largest tallest building. Its observatory on the 118th and 119th floor is one of the most popular places to enjoy the city skyline, with 30 percent of visitors being foreigners.

The coronavirus outbreak forced the building to close its observatory to visitors on January 24. It reopened on March 12, but will close again on Monday.

Another landmark in Lujiazui, Jin Mao Tower also reopened its observatory on the 88th floor on March 12, and it will also close from Monday.

Twenty-five indoor tourist attractions have been ordered to close their indoor sections from Monday. In addition, 37 outdoor tourist attractions with limited indoor space have been required to close their indoor areas, including Shanghai Wild Animal Park, City Beach, and Chenshan Botanical Garden.

Twelve scenic areas originally scheduled to reopen soon have been ordered to delay and venues which have not reopened yet are ordered to remain closed.
