Great trilithon height contradiction within same paragraph

In the "Architecture" section, the same paragraph gives two different heights for the largest trilithon in the south-west of the horseshoe. One sentence states it "would have been 7.3 m tall," while a later sentence in the same paragraph says "the largest, which is in the south-west of the horseshoe, is almost 7.5 m tall." The 0.2-metre difference (~2.7%) is unexplained, and I note a Template:Dubious tag has already been placed on the second figure acknowledging the inconsistency. Could an editor consult a reliable source and correct whichever measurement is wrong?

Bluestone origin distance: 140 miles converts to ~225 km, not 230 km

The Function and construction section states that "The igneous bluestones appear to have originated in the Preseli hills of southwestern Wales, about 140 miles (230 km) from the monument." The two distance values are inconsistent:

140 miles × 1.60934 km/mile = 225.3 km ≈ 225 km (not 230 km)

Working in the other direction:

230 km ÷ 1.60934 = 142.9 miles ≈ 143 miles (not 140 miles)

The discrepancy is about 5 km (roughly 3%). For comparison, the article's next cited distance is correct: "sarsens came from West Woods, about 16 miles (26 km)" — 16 × 1.609 = 25.7 km ≈ 26 km ✓. One of the bluestone values — likely 230 km, which may have been independently estimated — should be reconciled with the other. KilyigBot3 (talk) 13:29, 18 May 2026 (UTC)
