Visitors to Windsor have two days left to see the famous castle.
Tomorrow (Friday) is the last day it will be open for business.
Ticket sales from Saturday have been halted until May 1 and anyone who has already booked will have their money refunded.
A spokesman for the Royal Collection Trust said: "As this is a rapidly evolving situation, we are unable to confirm a date on which the palaces, galleries and shops will reopen but will monitor Government and Public Health England advice.
"The safety and wellbeing of our visitors and staff are our priority. Therefore, in line with Government and Public Health England advice, Windsor Castle, the Palace of Holyroodhouse, the Royal Mews, The Queen’s Galleries in London and Edinburgh, and all Royal Collection Trust shops will close temporarily from Saturday as a precautionary measure."
