These tile panels are on the outside wall of a mosque on Kingsland Road (north of Liverpool Street). It's on the corner of Laburnum Road. This style of Islamic floral designs is known as Iznik, named after the town in Turkey where the production of these kind of tiles was centred. Although Iznik tiles were first being produced around 500 years ago, they became popular in western Europe in the late1800s. Authentic ones were used at Leighton House in Holland Park, London, but the ones in the panels here are modern tiles with traditional patterns.
