What St Augustine Lighthouse & Maritime Museum does
Mission
To discover, preserve, present and keep alive the story of the nation's oldest port, as symbolized by our working St. Augustine Lighthouse.
As stated on its FY2025 Form 990.
Programs
Historic Preservation and Maintenance - In order to fulfill its mission, the Museum performs historic preservation on several historic structures, including the Saint Augustine Lighthouse. The Light Station was restored to U.S. Department of Interior standards. The keepers' house, light tower, the WWII Jeep garage, the summer kitchens, the Fresnel lens, the lantern and restorations consume approximately 20 percent of the operation's staffing hours. The site is listed on the National Register of Historic places and in 2010 the Museum achieved its Smithsonian Affiliate status. The museum maintains the aid to navigation as a private aid and keeps the light shining.

Interpretive and educational services were fully part of all programs for the 47,000 +/- school age children that visited and the 200,000 +/- annual visitors. Various services offered included the "Wrecked" exhibit, the Lighthouse Summer Camp scholarship program for at-risk children, the Behind-the-Scenes tours included with paid admission, and various programs within the Maritime Archaeology Specialty Programs. All program content was tied to and teaches Science, Technology, Engineering, and Math (STEM_ education and the Museum Mission. The Museum performs scientific research in the waters of the nation's oldest port city and cares for up to 13,000 artifacts, archaeological specimen, and historic archival documents. Some 3,000 objects are on long-term loan from the State of Florida.
Maritime Archaeology - The research arm of the Museum is the separately incorporated Lighthouse Archaeological Maritime Program (LAMP). LAMP archeologists host various field school students from across the United States, giving these students and other students hands-on experience in the field. LAMP has been working on a 1782 shipwreck site and objects such as a Queen Anne pistol, ship's deck pump,ship's bell, and various others have been retrieved by student divers. Current conservation work on these objects is supervised by the Museum. Fully conserved objects are displayed at the Museum's "Wrecked Exhibit" under permit by the State. LAMP publishes an annual archaeological research report that is presented to the State of Florida Division of Historical Resources. During the year, volunteers donate their time to build a variety of small craft and to tell and share stories of the maritime heritage to the vast number of tourists visiting the town.

The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $6.3M to $7.8M (+24%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2018 10% · 2019 2% · 2020 4% · 2021 14% · 2022 13% · 2023 13% · 2024 3% · 2025 3%. Grants only. Government contracts and fees sit inside program revenue.
14% of St Augustine Lighthouse & Maritime Museum’s revenue is contributions — more earned-revenue than three-quarters of its peers (63% for the typical peer).

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $200 → $22k.
2 of 8 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 36% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of St Augustine Lighthouse & Maritime Museum’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
St Augustine Lighthouse & Maritime Museum leans on a few funders — its largest provides 58% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
98% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund St Augustine Lighthouse & Maritime Museum.
Largest funder’s share by year: 2018 100% · 2019 98% · 2020 85% · 2021 98% · 2022 96% · 2023 99% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
25% of St Augustine Lighthouse & Maritime Museum's funders are still giving 3 years after their first grant; 88% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
97% of St Augustine Lighthouse & Maritime Museum's grant income comes from Florida funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $63k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
