The newest county park is home to the oldest lighthouse in Michigan!
The five-acre retired Coast Guard Station property was officially transferred to
St. Clair County Parks from the United States Coast Guard in 2010.
The Fort Gratiot Light Station is located next to the new Coast Guard Station in
Port Huron and includes the Fort Gratiot Lighthouse (1829), which is the oldest
lighthouse in Michigan.
The Light Station also includes the Light Keeper’s Duplex (1874), Fog Signal
Building (1900), Single Keeper’s Dwelling (1932), former Coast Guard Station
(1932), Equipment Building (1939), and a three bay garage (1990’s).
The agreement with the Federal Government requires St. Clair County Parks to
oversee the restoration of the site, following the Historic Structures Report.
The report is a guideline for how the site should be restored, beginning with
the light tower. Following the report, restoration of the tower began in the
fall of 2011 and was completed in the spring of 2012. The Port Huron Museum is
responsible for tours of the lighthouse, which are available May through
December. For information on tour fees or other museum sponsored programs, call
The restoration of the tower was made possible by a Save America’s Treasures
Grant and a match from the city of Port Huron. The tower is expected to be
reopened for tours in the summer of 2012. Once reopened, the Port Huron Museum
will serve as a partner in leading tours of the lighthouse.
All improvements to the site are being completed with various grants. In the
fall of 2011, roof repairs were made to the Fog Signal Building and the
Equipment Building using grants from the Michigan Lighthouse Assistance Program
(MLAP). The matching funds were provided by the Friends of the Fort Gratiot
An interpretive master plan will soon be adopted that will serve as a guideline
on how the history of the site will be interpreted.
The Park is open daily from 7:00am to 10:00pm. Admission to the park grounds is
free. Admission tickets are sold in the gift shop for tours of the station and
tower. The park is located at 2800 Omar Street, in Port Huron.

Light Station History
The newest county park is home to the oldest light house in Michigan!
As the shipping needs on the Great Lakes increased in the 1820’s, so did the
need for a navigational aid at the mouth of the St. Clair River. In August of
1825 the first lighthouse in Michigan was built at Port Huron. The original
tower was located near the base of the present day second span of the Blue Water
Bridge. It was 32 feet high above ground level, 18 feet in diameter at the base,
and tapered to 9 feet across at the top. The original tower did not last long,
as poor construction and September storms would lead to its demise when it
crumbled in November of 1828.
In early 1829, Congress appropriated funds to build the
second Fort Gratiot
lighthouse. In April of that year, Lucius Lyon was awarded the contract for
construction of the new lighthouse. This time the tower was built further north
so it could be clearly seen by ships approaching the mouth of the St. Clair
River from Lake Huron.
Lyon, who would later serve as one of the state’s first senators, contracted with
Truman Beecher to construct the tower. Plans called for a 65 foot high tower of
stone or brick, 25 feet wide and 5 feet thick at the base tapering to 12 feet
wide and 2 feet thick at the top, with an octagonal iron lantern. The plans also
called for the construction of a brick or stone keeper's dwelling. The contracted
price was $4445, with an extra $55 budgeted for adding the old Argon lamp in the
In the 1850’s, The Lighthouse Board began a series of reforms that would affect
the Fort Gratiot light. The first such change was the addition of a Fresnel
Fort Gratiot’s first Fresnel was a fourth order lens ordered directly from
France. It arrived in January of 1857. As the traffic on the Great Lakes
increased in the 1850s and 60s, so did the need for improved navigational aids.
New towers around the Great Lakes were being built at an average height of 80 to
100 feet tall to improve visibility. In 1862, the tower was raised to 82 feet
to accommodate the Fresnel lens’s superior range. That new addition can still be
visibly seen today. From the 1860’s to the 1930’s the property expanded with the
addition of the Keeper's Duplex (1874), the Fog Signal Building (1900), the Single
Keeper's Dwelling (1932), the Coast Guard Station (1932) and the Equipment
When most of the Great Lakes lights were automated in the 1930's, the need for
light keepers faded into the sunset. The Coast Guard maintained the Fort Gratiot
Light Station from the 1930's until they moved next door into the new station
that was built in 2004.
