Situ puts 1,000+ architectural landmarks on a map in your pocket — read who built each one and why it matters, and keep a list of the places you love.


Point your attention at a building and Situ tells you what you're looking at — curated, editorial, and quietly in the background.
A curated catalog of architectural landmarks, each with its architect, year, style and function — and the story behind the façade.
Every site is a category pin on the map, and dense areas cluster into counts. Tap one to see exactly what you're standing in front of.
Search the whole catalog by name and filter it down to what you're curious about, with the distance to each site from where you are.
Save the places you love and mark the ones you've been to. Both lists live on your device, with a running tally of states, styles and architects.
Spot a missing landmark or a mistake? Submit it or flag a correction — contributions go through editorial review before they're published.
No account to create, no ads, and no behavioral tracking — just anonymous crash reports so we can fix bugs. Your location is used on-device to find what's nearby.
