Western Stone
The Western Stone is a monolithic ashlar block of limestone integrated into the lowest course of the western retaining wall of Jerusalem's Temple Mount, renowned as one of the largest and heaviest stones ever maneuvered into position by ancient construction techniques.[1][2] Measuring 13.55 meters (44.5 feet) in exposed length, approximately 3 meters (10 feet) in height, and with an estimated depth of 3 to 4.5 meters (11 to 15 feet), it weighs around 517 metric tons, making it a testament to Herodian engineering prowess.[3][4] Placed as part of the expansive platform built by Herod the Great circa 19 BCE to support the enlarged Second Temple, the stone exemplifies the scale of megalithic masonry employed in antiquity, with its precise dressing and transport methods remaining subjects of scholarly intrigue due to the absence of modern machinery.[5][6] Visible only within the Western Wall Tunnels excavated in the 19th and 20th centuries, the stone forms the southernmost element of the "Nidbach Raba" or Great Course, a row of exceptionally large blocks stabilizing the Temple Mount's foundation against seismic and structural stresses.[1][6] Its quarrying from nearby limestone beds and relocation—likely via earthen ramps, rollers, and levers—highlights the logistical feats of Herod's workforce, comprising thousands of laborers over decades, though exact methodologies evade definitive reconstruction absent contemporary records.[7] Archaeologically, the stone's marginal drafting and anathyrosis joints align with Herodian stylistic hallmarks, distinguishing it from earlier or later phases of the site's fortification history.[5] As a surviving relic of the Temple complex destroyed in 70 CE, it underscores the enduring durability of ancient Judean architecture amid successive conquests and reconstructions.[2]Physical Description
Dimensions and Weight
The Western Stone, situated within the Western Wall tunnels north of Wilson's Arch, is a monolithic limestone block measuring approximately 13.6 meters (44.6 feet) in length, 3.3 meters (10.8 feet) in height, and with an estimated depth ranging from 2 to 4.6 meters (6.5 to 15 feet).[6][1] These dimensions position it as one of the largest cut stones employed in ancient construction, with its length visible along the wall's facade and depth inferred from surrounding masonry and excavation data.[2] Its estimated weight exceeds 500 metric tons, with calculations commonly placing it at around 570 tons based on volume assessments using a limestone density of approximately 2.7 tons per cubic meter.[8][9] Variations in weight estimates, such as up to 660 tons in some analyses, arise from uncertainties in the precise depth and minor differences in assumed material density, but peer-reviewed archaeological surveys affirm the 570-ton figure as representative.[6] The stone's mass underscores the engineering prowess of Herodian-era builders, as it forms part of the retaining wall's foundational courses without visible joints or supports beneath.[2]| Dimension | Approximate Value | Notes |
|---|---|---|
| Length | 13.6 m (44.6 ft) | Fully exposed along wall facade[6] |
| Height | 3.3 m (10.8 ft) | Measured vertically in situ[1] |
| Depth | 2–4.6 m (6.5–15 ft) | Estimated from embedded position and adjacent stones[2] |
| Weight | ~570 metric tons | Derived from volume and limestone density[9][8] |
