In 1874 it was discovered that the keystones had dropped and the arches were propped up with timbers. The steady increase in horse and cart traffic led to complaints that Temple Bar was becoming a bottleneck, holding back the City trade. In 1878 the City of London Corporation, eager to widen the road but unwilling to destroy so historic a monument, dismantled it piece-by-piece over an 11-day period and stored its 2,700 stones carefully. In 1880 the brewer Henry Meux, at the instigation of his wife Valerie Susan Meux, bought the stones and re-erected the arch as the facade of a new gatehouse in the park of his mansion house Theobalds Park in Hertfordshire, the site of a former substantial prodigy house of James VI and I. There it remained, positioned in a woodland clearing, until 2003. A plaque marks the site where Temple Bar once stood.
