The clock hands of Elizabeth Tower have been removed during maintenance and restoration work in the Palace of Westminster.
The tower is undergoing a £61m refurbishment, up from the original estimate of between £29m and £45m.
The clock hands will be replaced with temporary ones while the originals undergo conservation work.
The London landmark chimed for the last time in August and will not sound until 2021.
The only exceptions will be on New Year and Remembrance Sunday.
Work to the clock dials includes repairing the glass and metalwork.
