Imam Hossein Square, (), is a square in eastern central Tehran, Iran. It was designed by Karl Schlamminger.
The Tehran trolleybus system terminated at Imam Hossein Square upon its opening in the early 1990s and as of 2005 all five routes of the system (routes 1âÂÂ5) were still doing so. However, routes 1 and 2 were discontinued sometime between 2005 and 2010, and the remaining routes serving Imam Hossein Square were cut back by about 1 km to Meydan-e-Shohada at an unknown date between 2011 and 2013.
