What is Building Guessr?
Building Guessr is a free, browser-based geography and architecture trivia game. Players are shown a photograph of a famous building, monument, or landmark and must guess its location on a world map. Each round also asks whether the structure is still standing, partially ruined, or demolished—adding a layer of historical knowledge to the geographic challenge.
The game draws inspiration from the popular GeoGuessr concept but focuses specifically on architecture: the buildings, bridges, towers, temples, and monuments that define the skylines and landscapes of cities and regions around the world. With no account required and no cost to play, Building Guessr is accessible to anyone with a web browser.
The Database
Building Guessr features a carefully curated database of 945 buildings from every inhabited continent. Each entry includes the building's name, country, city, year of construction, current structural status, a brief historical description, and a hint to help players who are stuck. All photographs are sourced from Wikipedia and Wikimedia Commons under open licenses.
How Scoring Works
Each round is scored on three components:
- Location accuracy (up to 1,000 points) — The closer your map guess is to the building's actual coordinates, the more points you earn.
- Status accuracy (up to 500 points) — Correctly identifying whether a building still stands, is partially ruined, or has been demolished.
- Time bonus (varies) — Faster answers earn additional bonus points.
Architecture Across the World
The database spans structures from ancient Egyptian pyramids built over 4,500 years ago to contemporary skyscrapers completed in the 21st century. Players encounter everything from Buddhist temples in Southeast Asia and Gothic cathedrals in Europe to Mughal palaces in India and Art Deco towers in the Americas.
Preservation and Lost Heritage
Not all buildings survive the passage of time. Building Guessr includes structures in various states of preservation to highlight the importance of cultural heritage protection. The "Lost Buildings" game mode specifically features structures that have been partially or fully destroyed.
For Educators and Students
Building Guessr is an effective supplementary tool for geography, history, and art education. The game encourages students to develop skills in geographic reasoning, cultural awareness, visual analysis, and historical thinking—all within an engaging and low-pressure format.
Technical Details
Building Guessr is a static, client-side web application with no backend server required. The entire game runs in the browser, with game state stored locally using the browser's localStorage API. The interactive map is powered by Leaflet.js with CARTO tiles, and building images are loaded from Wikipedia's media servers at runtime. The game supports offline play as a Progressive Web App (PWA).
Open Source and Community
Building Guessr is independently operated and not affiliated with Wikipedia, Wikimedia, or GeoGuessr. We welcome feedback, building suggestions, and bug reports through our contact page.
How we curate the database
Every building in the database was added through a manual review process. We start with Wikipedia articles that have a freely licensed image on Wikimedia Commons, verified geographic coordinates, and a clearly documented standing status. Structures are included if they are architecturally or historically significant, visually distinctive in photographs, and geographically diverse enough to contribute to the game’s global spread.
Standing status classification uses three categories: Yes (the building is substantially intact and in recognizable form today), Partial (significant original fabric survives but the building is ruined, heavily damaged, or has lost major elements), and No (the structure has been demolished or destroyed beyond meaningful recognition). We err toward Partial for ancient ruins whose main walls and plan are still readable, and toward No only when photographs show nothing but a foundation or bare site.
Difficulty is assigned based on how recognizable a building is likely to be to a general audience without specialized knowledge. Easy buildings are globally famous landmarks; Hard buildings are nationally significant but less internationally known, or are frequently confused with other structures in the same tradition.
Why preservation matters
The Lost Buildings mode exists because the game’s database is partly a record of what has been lost. Wars, earthquakes, fires, and deliberate demolition have removed irreplaceable structures from the world’s cultural heritage. The Buddhas of Bamiyan, destroyed by the Taliban in 2001. The old city of Aleppo, severely damaged in the Syrian civil war. The National Museum of Brazil, destroyed by fire in 2018 with millions of irreplaceable specimens and artifacts. The Church of the Nativity in Bethlehem, damaged by crossfire in 2002. These are not abstractions—they are specific losses that impoverished our collective understanding of human history.
Building Guessr does not advocate for any specific preservation policy, but the act of learning to recognize and locate buildings fosters the kind of familiarity that makes loss meaningful. Players who have spent time placing Palmyra on a map or identifying the Mostar Old Bridge are more likely to care about their fate than those who have never encountered them. That is the strongest case for this kind of educational game.
Using Building Guessr in the classroom
Geography and history teachers have used Building Guessr as a warm-up activity, an end-of-unit review tool, and a supplement to textbook learning. The daily challenge’s fixed five-building set makes it easy to compare scores across a class without students having seen each other’s answers. The game’s combination of visual recognition, map placement, and historical knowledge (the standing status question) covers skills relevant to multiple learning objectives.
Practical classroom tips: use the Region filter to align the game with the geographic unit being studied; use the Era filter to focus on a historical period; use Hard difficulty once students have built baseline familiarity; and use the result screen’s Wikipedia link as a jump-off point for further research. There is no multiplayer or class dashboard yet—score comparison is done verbally or via screenshot—but this is a feature under consideration for a future version.
