Mecklenburgh Square on the east was named after Queen Charlotte, formerly Princess of Mecklenburg-Strelitz and was designed by Joseph Kay with Cockerell as consultant, Cockerell having fallen out with the Hospital Governers. The houses in the square were built between c1810-1820, with the gardens laid out by Kay in 1809-10. On the north side are early C19th cast-iron entrance gates and railings with square plan gate piers with moulded panels and roundels, surmounted by twisted lamp bases (lamps missing). The layout remains close to the original design with mature plane trees, ornamental trees, formal lawns and gravel paths. One section is devoted to New Zealand species.
