Mourners filing past the Queen's coffin wore out the stone floor of Westminster Hall
The floor of Westminster Hall has been worn - exposing some areas of bare stone - after thousands paid their respects when the Queen was lying in state.
More than 250,000 mourners are estimated to have queued to see the monarch's coffin in September.
Carpet was used at one stage to reduce the impact of those filing past.
Westminster Hall is the oldest remaining part of the original Palace of Westminster, which dates from 900 years ago, and has great historical and architectural importance.
It is used for ceremonial addresses and public exhibitions.
A House of Lords spokesperson said: "As a consequence of the high-level continuous footfall through Westminster Hall during the lying in state some delamination to the Yorkstone floor has occurred.
"It has exposed some areas of bare stone that will blend in with the surrounding areas over time. This does not present a structural risk."
At one point the line stretched from parliament along the south bank of the Thames and past Tower Bridge to Southwark Park.
David Beckham was among those to pay their respects.
On two occasions, the Queen's children and grandchildren held vigils around the coffin as the public continued to file past.

During the lying in state, which lasted four days, one of the noticeable sounds in the hall was the lone banging of a stick on the stone floor to signal the replacing of the guard every 20 minutes.
The Queen was buried beside Prince Philip in a final private ceremony in St George's Chapel in Windsor.
