Stonehenge trilithon
A Stonehenge trilithon is a prehistoric monument feature consisting of two upright stones supporting a horizontal lintel at Stonehenge.
Also known as: Stonehenge great trilithon
How big is it?
7.3 m tall
Also 23.95 ft
Approximate reconstructed height · approximate
Typical recorded range: 6.7 m to 7.5 m.
A little perspective
About the same scale as Apollo lunar module.
Apollo lunar module: The Apollo lunar module was a two-stage spacecraft used by NASA to land astronauts on the Moon and return them to lunar orbit during the Apollo missions.
Measurements, assumptions & sources +
Stonehenge trilithon
A representative great trilithon at Stonehenge reconstructed to approximately 7.3 m high and 6.5 m wide. Fallen, incomplete stones and uncertain original surfaces make the dimensions approximate.
The marked approximate reconstructed height is calibrated. Unmeasured illustration details are representative.
Apollo lunar module
The Apollo lunar module was about 7.04 m high. The 15,103 kg value is the Apollo 11 lunar module at separation, including descent and ascent stages; mission configurations differed.

Why this measurement?
Why we use 7.3 m
For comparison, this page uses approximate reconstructed height. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 6.7 m to 7.5 m.
