Kangwon City Builder

Scroll through hundreds of the world's most iconic structures, from the spiraling glass facade of Shanghai Tower to the ancient stones of the Colosseum, each with its height, floor count, construction history, and facts you probably never knew. The catalog is organized by category so you can go straight to historical monuments, luxury hotels, or record-breaking skyscrapers without digging through everything at once. Tap any building and the detail screen fills with context that actually makes you stop and read. Some buildings on the ratings list you will recognize instantly, others will make you wonder how you never heard of them before.
