Today we're flipping the switch on the biggest expansion in CityHenge's history: 28 new cities across the United States, Canada, the United Kingdom, France, Germany, Spain and the Netherlands.

That takes the total to **45 cities across 8 countries** — and every one of them has full sun and moon alignment data, computed nightly and cached for offline use, exactly the same as the launch cities back home in Australia.

**The new cities:**

- **United States (10)** — New York (yes, including Manhattanhenge), Los Angeles, Chicago, Houston, Phoenix, Philadelphia, San Antonio, San Diego, Dallas, Jacksonville - **Canada (3)** — Toronto, Montreal, Calgary - **United Kingdom (3)** — London, Birmingham, Glasgow - **France (3)** — Paris, Marseille, Lyon - **Germany (3)** — Berlin, Hamburg, Munich - **Spain (3)** — Madrid, Barcelona, Valencia - **Netherlands (3)** — Amsterdam, Rotterdam, The Hague

**Why these cities, and how we picked them**

Every city in the supported set has been imported from OpenStreetMap, with each street's bearing computed and matched against the sun and moon's position for every day of a rolling 14-day window (90 days for Pro, 365 for Founders). Manhattan was an obvious starter. So were the iconic grid cities — Chicago, Barcelona, Madrid — where the alignment phenomenon is at its most theatrical. The rest are a deliberate mix of latitudes, climates and street planning histories: organic Roman roads in London, Haussmann's designed axes in Paris, Cerdà's rigorous Eixample in Barcelona, Penn's 1682 grid in Philadelphia, the modernist post-war rebuild in Rotterdam.
