Explore American History Through Interactive Maps

When It Was curates collections of historic locations that tell a story bigger than any single place. Each collection maps the real addresses behind America's most fascinating history - the speakeasies where jazz was born, the mansions where ghosts still walk, the casinos that built Las Vegas, and the lunch counters where the civil rights movement began.

Unlike static history articles, our collections are interactive. Every location is plotted on a custom-styled map with full details: addresses, dates, descriptions, and what's there now. Filter by category, switch between map and list view, and click through to explore each location on our full map with historical photos and community stories.
