Mosaic marking what is believed to be the site of an oak (Quercus), or possibly an elm (Ulmus), around which members of the Reform League, which campaigned for the right of all adult men to vote, gathered in the 1860s.  The original tree is said to have been burnt down in a ‘riot’ in 1866.  Protestors continued to meet near its stump, though later such activities moved to nearby Speakers’ Corner.
