Recent findings (audit lane, verbatim)

Taipei 101 — The building's architectural height is 508 m, not 509.2 m.

Taipei 101 — As of 2024, Taipei 101 is approximately the 12th tallest building in the world, not 11th.

Tate Modern — The visitors figure for 2025 is stated as 4,514,266, but the entry itself notes this is a 2023 figure and 2025 data is not yet available. Claiming it as a 2025 figure is factually incorrect.

Tate Modern — The 'DID YOU KNOW' section states 'In 2025, Tate Modern had 4,514,266 visitors', which is false because 2025 has not occurred yet and the figure is from 2023.

Willis Tower — The building's height is 1,451 feet (442 m) to the roof, not 1,450 feet; the official architectural height including the roof is 1,451 feet (442.1 m).

Willis Tower — The Skydeck is not the highest observation deck in the United States; One World Trade Center's One World Observatory (at 1,268 feet) and other decks are higher, though the Skydeck's elevation (1,353 feet) is often cited as the highest in the U.S. for a buildin

Winter Palace — The entry states the palace has 1,786 doors and 1,786 windows, but the widely cited canonical figure is 1,786 doors and 1,945 windows.

Winter Palace — The entry says the present palace was 'built and altered almost continuously between the late 1730s and 1837', but the present (fourth) Winter Palace was built from 1754 to 1762, not from the late 1730s.

World Trade Center (1973–2001) — The idea of a World Trade Center in New York City was first proposed in 1943, but it was actually first proposed in 1946.

World Trade Center (1973–2001) — The description that the site was originally under the Hudson River and later became Radio Row is misleading; the site was created by landfill extending the shoreline, and Radio Row existed there before demolition.

Yasukuni Shrine — The entry states the shrine was founded by Emperor Meiji in June 1869, but it was established by the Meiji government, not directly by Emperor Meiji as a personal act.

Yasukuni Shrine — The entry says the shrine's purpose 'has been expanded to include war dead from the Meiji, Taishō, and early Shōwa periods,' but the shrine from its inception included war dead from the Boshin War and later conflicts, so this is not a later expansion.
