Despite no trace of the theatre remaining today, a memorial plaque was unveiled in 1951 at its site at 225 Westminster Bridge Road.

On Friday 14th September 2018, on the initiative of Martin 'Zippo' Burton of Zippo's Circus, a commemorative 'paver' or flagstone was inaugurated in the garden of St Thomas's Hospital, a reminder that Astley's once stood on that spot

The Amphitheatre was again rebuilt, this time in the style of rival Charles Hughes's Royal Circus with lavish decorations and reputedly the largest stage in London.

[3] With increasing prosperity and rebuilding after successive fires, it grew to become Astley's Royal Amphitheatre and this was the home of the circus.

[6] Edward Tyrrel Smith succeeded Boucicault and provided Adah Isaacs Menken with her first London appearance in Mazeppa to "overflowing houses".

The pit used for the entertainers and riders became a standardised 43 feet in diameter, with the circular enclosure surrounded by a painted four foot barrier.

[14]Jane Austen's 1815 novel Emma credits a visit to Astley's for bringing about the reconciliation and engagement of Robert Martin and Harriet Smith.
