In 1825, while George IV. was on the throne, old Buckingham Palace was found to be in such a dilapidated condition that thorough repair was absolutely necessary, and after much hesitation it was decided to erect a new and improved mansion, whilst retaining the old site and dimensions. The important task was confided to John Nash, an architect much esteemed by the king, and the result was the clumsy building in the so-called revived classic style, with which we are all only too familiar.
On the accession of Queen Victoria, it was found altogether inadequate to its purpose, and Nash's triangular structure, at that time entered from the Marble Arch, which now stands at the north-east end of Hyde Park, was supplemented by a number of new buildings on the north side by Blore, including the private chapel, consecrated in 1843, with pillars from the celebrated screen of old Canton House.
