Where 452 fits
Why 452 is special
They held the tallest-building record from 1998 to 2004 on a technicality: their spires counted as architectural features while the Sears Tower's antennas did not. The rule governing what counts as height is genuinely contested.

CDLII uses the subtractive pair CD: a hundred before five hundred — five hundred minus a hundred.

Read as powers of two: 256 + 128 + 64 + 4 = 452.
In historical numeral systems
Egyptian
4 coils of rope, 5 hobbles, 2 strokes
4 × 100 + 5 × 10 + 2 × 1 = 452. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
7 vertical wedges (sixties place), 3 corner wedges + 2 vertical wedges (units place)
7 × 60 + 32 = 452. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
upsilon, then nu, then beta, marked as a numeral
upsilon-nu-beta + keraia
upsilon + nu + beta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then nun, then bet
tav-nun-bet
tav (400) + nun (50) + bet (2) = 452, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
The Petronas Towers took the height record in 1998 because spires count as architecture and antennas do not. The Burj Khalifa exceeded it by a margin large enough that the definition stopped mattering.

Technology & computing
The Petronas Towers were recognised as the world's tallest building at 452 metres in 1998 on the basis that their spires are architectural features rather than antennae, a distinction that decided the record.
