The Story of Poles Hill - Poles Hill was once known as Beacon Pole Hill, so named because of a ship’s mast mounted on the highest point of land along the eastern boundary above Wheeler Street.
Poles Hill is an Acidic Rocky Summit shrubland. Natural shrublands are among the most endangered ecosystems in the United States. Absent disturbances such as fire or wind, trees eventually overtop the shrub layer.
There are a number of species that are dependent on shrublands and other "early successional" areas such as abandoned fields. These include many bird species and the New England cottontail.
There are several perched wetlands on Poles Hill, including a deep marsh, a shallow marsh, and a shrub swamp. Several of these wetlands and surrounding areas may contain vernal pools. Back
Native American Uses of Poles Hill - Native Americans living on Cape Ann before and during European contact used Poles Hill as a solar observatory, ceremonial landscape, and gateway to the spirit world. Beginning more than 2,000 years ago, the people observed sight lines between certain large boulders and the horizon, shown on the maps. By these sightings, they determined the timing of astronomical events, such as the summer and winter solstices and spring and fall equinoxes. Native Americans used these and other dates to organize their annual calendar of religious observances and economic activities.

The Friends of Poles Hill formed in 1997 when neighbors and friends learned of a proposal to build 40 houses on this unique coastal heath, based on a development plan approved in 1962. The proposed plan later grew to 110 units of cluster housing, which would have destroyed the ledges, wildlife, blueberries, hiking trails and spectacular views that make Poles Hill a landmark on Cape Ann.
The Friends of Poles Hill worked for nearly two years with one goal in mind: save it all. This work involved mediation with the developer, and educating the public, not only to the beauties of Poles Hill, but to the dangers when open space is lost to over-development: increased run-off to the Annisquam and Mill Rivers below, more traffic on already busy streets, more classrooms for new school students, and the increased cost of fire and police protection and other City services.
Help came from many directions: The Commonwealth of MA awarded the effort a $500,000 grant, the Essex County Greenbelt established and managed an earmarked fund for Poles Hill, and many local citizens and businesses donated money and services. The final chapter was the decision to put the question to the voters: a Proposition 2 1/2 override to purchase Poles Hill was put on the ballot for the 1998 election. On Nov. 3, 1998, every ward and precinct in Gloucester voted to save Poles Hill. Back
