Lovecraft's works directly. 🐙 Innsmouth is a seaside town in Essex County, Massachusetts run by the Esoteric Order of Dagon and their Deep One allies until their destruction in 1928.


The Manuxet river runs through the centre of town, before turning southward to join the ocean at the end of the harbour's breakwater.

Newburyport is an hour's bus ride down the coast.


Founded in 1643, Innsmouth was noted for ship-building before the American Revolution, after which the civic centre shifted to the present Town Square. It reached its peak as a naval hub after the War of 1812, when many of its privateering sailors were killed. As a result, there was a dip in trade for both the shipping families and local mills.

In 1846, Captain Marsh and 32 fellow cultists were arrested by Selectman Mowry. However, before they could be charged, the Deep Ones stormed the town, breaking them out and purging the resistant population. Half of the population were killed in what was covered up as a plague from China.

After the American Civil War, the last big ships stopped docking in the harbour.

It became something of an industrial centre at one point, but by the 1920s, only the Marsh Refining Company gold mill is still in operation.

After Robert Olmstead escaped Innsmouth on July 16, 1927, and reported the going-ons to authorities, a large force of federal agents laid siege to the town throughout the winter of 1927-28, demolishing most of its seafront buildings. It was later reported in February 1928 as a prohibition related clash though no captives ever showed up in the prison system. It included several arrests of members of the Esoteric Order of Dagon and at least one torpedo fired into Devil's Reef.


After the 1846 massacre, there were about 300-400 people living in Innsmouth, many of whom were Deep One hybrids. A number of Polish and Portuguese migrants tried moving into the area before being "scattered in a peculiarly drastic fashion".

As it fell into disrepair under the control of the Deep Ones, by 1927, the town lacked a public library or a chamber of commerce. Many of the street signs had also been removed, making navigation difficult for outsiders.
