Not a lot of people know that, but the House of Lords holds robes that are lent to peers for ceremonial use on state occasions.

The robes have been donated or bequeathed to the House of Lords by former members, and are cleaned and repaired as and when necessary.

The value was £217,453 as at 31 March 2015*, according to a report pointed to in a response to a written parliamentary question on the topic.

Here’s a link to the House of Lords resource accounts for 2014-15.

* The value of member robes was apparently based on an indicative valuation for purposes of insurance and the robes, due to their long life, are not depreciated.
