Located near the Royal Exchange, it is underground, accessed by descending down a flight of stairs. London's first public flush lavatories were situated near here, and opened in 1855, inspiring the following celebratory poem by Josiah Feable:
Down gleaming walls of porc'lain flows the sluice
That out of sight decants the kidney juice
Thus pleasuring those gents for miles around
Who, crying for relief, once piped the sound
Of wind in alleyways...
Users back in those days were charged one penny to use the facilities; today this particular location is free of charge."
