By 1811, there were 53 houses and four streets. The pier was extended in 1821 and the population peaked in the same year, when the island had 221 people. There were three schools, a Wesleyan chapel, and three public houses, mostly used by visiting sailors. Following major improvements to nearby

Several houses are built on the hillside facing Marazion, and a spring provides a natural flow of water. There is a row of eight houses at the back of the present village; built in 1885 they are known as Elizabeth Terrace. Some of the houses are occupied by staff working in the castle and elsewhere on the island. The mount's cemetery (currently no public access) contains the graves of former residents of the island and several drowned sailors. There are also buildings that were formerly the steward's house, a changing-room for bathers, the stables, the laundry, a barge house, a sail loft (now a restaurant), and two former inns. A former bowling green adjoins one of the buildings. The population of this parish in 2011 was 35.

Folklore

In prehistoric times, St Michael's Mount may have been a port for the tin trade, and Gavin de Beer made a case for it to be identified with the "tin port" Ictis/Ictin mentioned by Posidonius. There are popular claims of a tradition that the Archangel Michael appeared before local fishermen on the mount in the 5th century AD. But in fact this is a modern myth. The earliest appearance of it is in a version by John Mirk, copying details of the medieval legend for Mont-Saint-Michel from the Golden Legend. The folk-story was examined and found to be based on a 15th-century misunderstanding by Max Muller. The chronicler John of Worcester relates under the year 1099 that St Michael's Mount was located five or six miles (10 km) from the sea, enclosed in a thick wood, but that on the third day of November the sea overflowed the land, destroying many towns and drowning many people as well as innumerable oxen and sheep; the ''

used the Mount as the setting for the finale of what was once one of the most famous poems in English literature, his "Lycidas", which drew on the traditional sea-lore that had it that the archangel Michael sat in a great stone chair at the top of the Mount, seeing far over the sea and thus protecting England. In the mid-1850s the poem's scenes of the drowning of Lycidas, in the seas below the Mount, were illustrated in engravings and paintings by

Legend

During the 6th century, before a castle was built, according to legend, the island St. Michael's Mount sits upon was once home to an 18-foot giant named Cormoran, who lived in a cave with his ill-gotten treasures obtained by terrorizing local towns and villages. That is, until a young farmer's son named Jack took on this gigantic menace, who had an appetite for cattle and children, and killed him by trapping him in a concealed pit, bringing down his axe upon his head. When he returned home, the elders in the village gave him a hero's welcome, and henceforth, called him "
