Size It Up Landmarks answer: September 20

The five Landmarks silhouettes for September 20, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 17 ran from the Qutb Minar (72.5 m) to One World Trade Center (541.3 m). The widest gap was round 5, Arena of Nîmes against One World Trade Center, at 4.1×; the closest call was round 1, Sydney Opera House against Petronas Tower 1, only 2.5× apart — the kind of round that separates a 90 from a 60.
