St. Martin's Le Grand
To the east of the road once stood the collegiate church and monastic precinct of St. Martin's, of ancient origin. The precinct was within the City, but was not subject to its jurisdiction, constituting a liberty with the privilege of sanctuary.
According to a somewhat dubious tradition the church dated back to the 7th or 8th century and was founded by King Wihtred of Kent. It was, more certainly, rebuilt or founded about 1056 by two brothers called Ingelric and Girard, in the reign of Edward the Confessor. This foundation was confirmed by a charter of William the Conqueror, dating to 1068. The church was responsible for the sounding of the curfew bell in the evenings, which announced the closing of the City's gates. It was dissolved by Henry VIII and demolished in 1548. However, it retained certain rights of sanctuary until 1697 and, as such, was a notorious haven for malefactors. One of those who sought sanctuary here was Miles Forrest, one of the reputed murderers of the Princes in the Tower.
General Post Office
The General Post Office established its new headquarters on the site of the monastic precinct in 1829. From here mail coaches departed for destinations all over the country. Coaches bound for the north went up St. Martin's Le Grand through Aldersgate – the first stage of the Great North Road (now the A1 road) to York and Edinburgh. This replaced the previous starting point at Hicks Hall in Smithfield Market. The Post Office building, a grand Neoclassical design by Robert Smirke, was demolished in 1911, having been replaced by new premises immediately to the west, on the former site of Christ's Hospital school.

St. Martin's Le Grand formed part of the marathon course of the 2012 Olympic and Paralympic Games. The women's Olympic marathon took place on 5 August and the men's Olympic marathon on 12 August. The four Paralympic marathons were held on 9 September.
