The Thomas Point Shoal Light, also known as Thomas Point Shoal Light Station, is a historic lighthouse in the Chesapeake Bay on the east coast of the United States, and the most recognized lighthouse in Maryland. It is the only screw-pile lighthouse in the bay which stands at its original site. The current structure is a 1½ story hexagonal wooden cottage, equipped with a foghorn as well as the light. [6]

History

A stone lighthouse was constructed in 1825 on shore at Thomas Point [1] by John Donahoo. It was replaced in 1838 by another stone tower. The point was subject to continuing erosion (which would eventually bring down the lighthouse on the point in 1894), [6] and in 1873 Congress appropriated $20,000 for the construction of a screw-pile structure. With an additional $15,000 appropriation in 1875, the light was built and activated in November of that year. [6] It took 30 workers to set each cast iron beam 12 ft (3.7 m) into the Chesapeake Bay's bottom. [7]

Ice was a perpetual threat to screw-pile lights on the Chesapeake, and in 1877 the original lens was destroyed when it toppled by shaking from ice floes. This lens was replaced, and the additional piles and riprap were placed around the foundation in order to protect it. By 1964 it was the last manned light in the Chesapeake Bay, and it was not automated until 1986. It is currently the last unaltered screwpile cottage-type lighthouse on its original foundation in the Chesapeake Bay.

Preservation

Concerns for its preservation brought it a National Register of Historic Places listing in 1975 [4] and National Historic Landmark status in 1999. [5] [8]

In 2004, ownership of the lighthouse passed to the city of Annapolis, Maryland, which now maintains the structure in conjunction with Anne Arundel County, Maryland, the Annapolis Maritime Museum, and the Chesapeake Chapter of the U.S. Lighthouse Society. In 2019, a Lighthouse Society spokesman said that the steel substructure, last replaced in the 1980s, is severely rusted and requires $300,000 in repairs. Fortunately, the cast iron screw pilings remain in sound condition, "as good today as they were 144 years ago", said the Baltimore Sun in reporting on the needed funding in August, 2019. [7]

The United States Coast Guard continues to maintain the navigational aids at the Lighthouse. The lighthouse keeper's former living quarters are open to the public three months out of the year, through organized boat tours departing from Annapolis . [9]

Screw-pile lighthouse lighthouse which stands on piles that are screwed into sandy or muddy sea or river bottoms

A screw-pile lighthouse is a lighthouse which stands on piles that are screwed into sandy or muddy sea or river bottoms. The first screw-pile lighthouse to begin construction was built by the blind Irish engineer Alexander Mitchell. Construction began in 1838 at the mouth of the Thames and was known as the Maplin Sands lighthouse, and first lit in 1841. However, though its construction began later, the Wyre Light in Fleetwood, Lancashire, was the first to be lit.

United States lightship <i>Chesapeake</i> (LV-116)

United States lightship Chesapeake (LV-116/WAL-538/WLV-538) is a museum ship owned by the National Park Service and on a 25-year loan to Baltimore City, and is operated by Historic Ships in Baltimore, Maryland. A National Historic Landmark, she is one of a small number of preserved lightships. Since 1820, several lightships have served at the Chesapeake lightship station and have been called Chesapeake. It was common for a lightship to be reassigned from one Lightship Station to another and thus "renamed" and identified by its new station name. Even though the "name" changed during a Lightship's service life, the hull number never changed. The United States Coast Guard assigned new hull numbers to all lightships still in service in April 1950. After that date, Light Ship / Light Vessel 116 was then known by the new Coast Guard Hull number: WAL-538. In January 1965 the Coast Guard further modified all lightship hull designations from WAL to WLV, so Chesapeake became WLV-538.
