Mansion House, London the columned "Egyptian Hall", was so named because Dance used an arrangement of columns deemed to be "Egyptian" by Vitruvius. No Egyptian motifs were employed. It has twenty niches for sculpture. There was originally an open courtyard, later occupied by a saloon. The residence used to have its own court of law, since the Lord Mayor is the chief magistrate of the City while in office. There were eleven holding cells (ten for men and one, nicknamed "the birdcage", for women). A famous prisoner here was the early 20th-century suffragette women's rights campaigner Sylvia Pankhurst. Mansion House is home to
