Size It Up Landmarks answer: September 17

The five Landmarks silhouettes for September 17, 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 14 ran from the Belém Tower (30 m) to the Burj Khalifa (828 m). The widest gap was round 3, Burj Khalifa against Palace of Culture and Science, at 3.5×; the closest call was round 1, Christ the Redeemer against Belém Tower, only 1.3× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Christ the Redeemer (with pedestal) vs Belém Tower (four-storey tower)

    Belém Tower · reference · 30 m
    Christ the Redeemer · true height · 38 m

    1.3× taller than the Belém Tower

    Christ the Redeemer is 38 m with its pedestal; the arms span 28 m.

  2. ROUND 2

    Big Ben (Elizabeth Tower) vs Verona Arena (exterior long axis, rounded)

    Verona Arena · reference · 152 m
    Big Ben · true height · 96 m

    1.6× shorter than the Verona Arena

    The clock tower is 96 m tall; Big Ben is strictly the 13.7-tonne bell inside it.

  3. ROUND 3

    Burj Khalifa vs Palace of Culture and Science (including antenna support)

    Palace of Culture and Science · reference · 237 m
    Burj Khalifa · true height · 828 m

    3.5× taller than the Palace of Culture and Science

    Burj Khalifa is 828 m tall — two and a half Eiffel Towers stacked.

  4. ROUND 4

    Washington Monument vs Sydney Harbour Bridge (main arch span)

    Sydney Harbour Bridge · reference · 503 m
    Washington Monument · true height · 169 m

    3.0× shorter than the Sydney Harbour Bridge

    The Washington Monument is 169 m — the world's tallest stone structure.

  5. ROUND 5

    Burj Al Arab (building height) vs Petronas Tower 1 (one tower, architectural height)

    Petronas Tower 1 · reference · 452 m
    Burj Al Arab · true height · 321 m

    1.4× shorter than Petronas Tower 1

    Burj Al Arab: 321 m height (building height). Base to the top of the sail-shaped hotel; not the helipad height.
