Architecture Bites brings great buildings to life, and does something no book and no other app does: collects humanity's greatest achievements in architecture, making them visible in precious, artistic three dimensional renders. Travel the world: there's a palace that floats on a lake in Rajasthan, and a hotel in Singapore that lays a ship across the tops of three towers - the world is full of architectural wonders that represent some of humanity’s greatest achievements. Every building also comes with its real story: what it is, the history behind it, the achievement of it. Architecture Bites is the classical grand tour - once reserved for the elite few - reimagined for the modern age. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
