Mapping the South: Building Our Heritage Sites Map

The American South is home to tens of thousands of heritage sites — battlefields and burial grounds, antebellum plantations and freedmen's schoolhouses, courthouses and camp meeting grounds, shotgun houses and grand Greek Revival mansions, iron bridges and tabby ruins. Yet no single, comprehensive, publicly accessible resource exists that maps these places in a way that is useful to researchers, travelers, educators, and preservationists alike.

That is about to change. The Southern Historic Preservation Society is building the Southern Heritage Sites Map — a free, interactive online map that will aggregate and display heritage sites across the region, organized by type, era, condition, and significance. And we are doing it entirely in-house, with our own staff, to keep development costs low and quality high.

Why an Interactive Map?

Heritage sites are, by definition, anchored to place. A written report or a database spreadsheet can describe a site's history and significance, but only a map can show you where it is — and, just as importantly, what is near it. Patterns of settlement, migration, industry, conflict, and community life become visible when heritage sites are plotted geographically. A cluster of freedmen's churches along a particular road in Alabama tells a story that no individual listing can convey. A string of antebellum cotton warehouses along a river reveals the infrastructure of an entire economic system.

Interactive mapping adds a further dimension: the ability to filter, search, and explore. Users will be able to view all sites of a particular type — say, Reconstruction-era schools — across the entire region, or zoom in to a single county and see every cataloged heritage site within it. Each site entry will include its name, location, approximate date or era, type, current condition, a brief historical description, and links to any related SHPS publications or resources.

Building It In-House

Many organizations outsource digital projects to external development firms — a process that can be expensive, slow, and difficult to maintain over time. The SHPS Heritage Mapping team made a deliberate decision to build this project internally. Our staff includes researchers with deep knowledge of Southern history and geography, and we are investing in the technical skills needed to design, populate, and maintain the map platform ourselves.

This approach has several advantages. First, it dramatically reduces development costs — a critical consideration for a nonprofit operating on member dues and donations. Second, it keeps institutional knowledge in-house: the people who build the map are the same people who understand the history behind every pin on it. Third, it ensures the project can be updated and expanded continuously, without depending on an outside contractor's availability or budget cycle.

The technical stack is deliberately simple and sustainable. We are using open-source mapping tools — including Leaflet.js and OpenStreetMap tile layers — to build a lightweight, fast, and mobile-friendly map interface. Site data is stored in a structured format that can be exported, backed up, and migrated as needed. No proprietary lock-in. No expensive licensing fees.

What the Map Will Include

The initial release will focus on sites that SHPS staff have personally researched and verified. These fall into several broad categories:

• Architectural landmarks — houses, churches, courthouses, commercial buildings, and other structures of historic significance
• Battlefields and military sites — Civil War battlefields, fortifications, military institutes, and memorial grounds
• Cemeteries and burial grounds — including historically Black cemeteries, family plots, and church graveyards at risk of being lost
• Cultural landscapes — plantation complexes, agricultural terraces, freedmen's communities, and other landscapes shaped by human activity
• Educational institutions — historically significant schools, colleges, and academies, including those that have closed or been demolished
• Industrial and infrastructure sites — mills, bridges, train depots, wharves, and other structures tied to the economic history of the region

Each site entry will be classified by its current condition — intact, at risk, partially demolished, demolished, or unknown — so that the map serves not only as a reference tool but as an early warning system for sites in danger.

How You Can Help: Submit a Site

We cannot do this alone. The South is vast, and heritage sites are everywhere — many of them known only to local communities, families, or individual historians. One of the most important features of this project is a public submission form that will allow anyone to suggest a heritage site for inclusion in the map.

The submission process is straightforward. Visitors to our website will be able to fill out a simple form providing the basic information we need to evaluate and catalog a site:

• Site name and location (address, coordinates, or general description)
• County and state
• Type of site (church, cemetery, house, battlefield, bridge, etc.)
• Approximate date or era of construction or significance
• Current condition (if known)
• A brief description of the site's historical significance
• Optional: photographs, documents, or links to additional information

Every submission will be reviewed by SHPS staff before being added to the map. We will verify the location, cross-reference it against existing databases (including the National Register of Historic Places, state historic preservation office records, and our own research files), and write a standardized description. Submitters will be credited by name unless they prefer to remain anonymous.

What This Means for Preservation

An interactive heritage map is not just a reference tool — it is a preservation tool. When a site appears on a publicly accessible, well-documented map, it becomes harder to ignore, easier to advocate for, and more likely to receive formal protection. Local preservation commissions, state historic preservation offices, and advocacy organizations can use the map to identify sites that merit nomination to the National Register of Historic Places. Developers and planners can use it to identify heritage resources before breaking ground. Educators can use it to design field trips and curricula rooted in local history.

For the public, the map will be a tool for exploration and discovery. Imagine planning a driving tour through the Mississippi Delta and being able to see, at a glance, every heritage site along your route — from a Civil War-era cotton gin to a freedmen's schoolhouse to a juke joint that helped shape American music. That is the future we are building.

The Southern Heritage Sites Map is currently in active development. We expect to launch the first public version in mid-2026, with an initial dataset of over 500 verified sites. The submission form will go live simultaneously, and we will continue to add sites on a rolling basis as submissions are received and reviewed.

If you know of a heritage site that deserves to be on the map — whether it is a grand plantation house or an unmarked freedmen's cemetery at the edge of a cotton field — we want to hear from you. Visit our Submit a Site page to get started.
