1 other organization in the IRS Business Master File lists the same street address. matched by us

We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2023

Mission

The LAMP is dedicated to the investigation, interpretation, and better understanding of the maritime history and archeology of St. Augustine, the "First Coast" region of Florida, and beyond.

Activities or mission (Part I)

To discover, preserve, present and keep alive the story of the nation's oldest port, as symbolized by our working St. Augustine Lighthouse.

  • Archaeological Research - The research arm of the St. Augustine Lighthouse and Maritime Museum is the separately incorporated Lighthouse Archaeological Maritime Program, LAMP. LAMP maintains an active program of both archival and archaeological research and employs archaeologists, a professional paleographer (expert on colonial Spanish script), and an archaeological conservator (specialist in the stabilization of waterlogged archaeological artifacts). LAMP maintains a conservation laboratory, diving locker, analytic laboratory, and also extensive databases of port records, ship losses, and other historical data. It is working actively to bring its stories to the public at the museum and has developed a heritage boat-building program as well as a field school and training workshops for university students, including scholarships for underserved individuals.

    Expenses $251,801

  • Maritime Archaeological Field School - LAMP oversees an intense accredited educational program allowing both undergraduate and graduate students the opportunity to participate in a marine survey and underwater excavation of a historic shipwreck site. In addition to methodological training and academic lectures, students get valuable real-world experience in all aspects of archaeological fieldwork, scientific diving and seamanship, and laboratory analysis.

  • Public Archeology - LAMP Boat-works is dedicated to keeping traditional wooden boat-building alive and relevant for new generations by focusing on the construction of traditional vessel types once common in the waters of St. Augustine and Northeast Florida. It also works with archaeologists to aid with the interpretation, reconstruction and experimental replication of archaeological boat and ship remains. LAMP also maintains a research library of thousands of books, reports, documents, papers and audio-visual media related to maritime history and archeology. Throughout the year, volunteers donate their time to build a variety of small craft, including skiffs and barca chata. The building of a Spanish chalup is an ongoing partnership with the St. Augustine Maritime Heritage Foundation and the Fountain of Youth Archaeological Park. An increased effort to bring more archaeological research to the public is a continuing effort.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

No itemized grant names this organization as a recipient. Only grants over $5,000 are itemized, and only by filers of the full Form 990.

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
