Tregeseal Entrance Grave - point cloud

This barrow was excavated in 1879 by WC Borlase. The chamber survives with two capstones still in place. It is oriented NW-SE, but we do not know which end was the original entrance. Finds include sherds, ashes (cremations), a whetstone in the chamber and a Middle Bronze Age ribbon handled urn in the cist. The urn is now in the British Museum. It is possible that the monument present today represents two phases - an original neolithic chambered barrow with a later Bronze Age cist, which may have also been when the mound was enlarged. The chamber is 3.8m long, averaging 1.2m wide. The north end is covered by two stone slabs for a distance of 1.9m. The internal height of the chamber is 0.7m. The mound denotes the extent of the barrow, marked by possible kerb stones.

该圆形封土冢（barrow）于1879年由W·C·博尔拉斯发掘。墓室尚存，两块盖顶石（capstones）仍原位留存。其朝向为西北-东南向，但目前无法确定哪一端为原始入口。出土遗物包括陶片（sherds）、火葬灰烬遗存、墓室中的一块磨石（whetstone），以及石棺（cist）内出土的一件中青铜时代丝带柄陶瓮。该陶瓮现收藏于大英博物馆。现存该遗迹可分为两个营建阶段：最初为新石器时代带墓室的封土冢，后期增设了一座青铜时代石棺，此次增设过程或同时伴随冢体扩建。墓室长3.8米，平均宽度1.2米；北端被两块石板覆盖，覆盖段长1.9米，墓室内部净高0.7米。冢体以疑似冢界石（kerb stones）标识范围，即现存封土的整体规模。「高清模型版本」：https://sketchfab.com/3d-models/tregeseal-entrance-grave-35f6b298b9094645a87a37c4e4dc96a5 本3D扫描件由策展研究中心（Curatorial Research Centre）为彭维斯景观合作项目（Penwith Landscape Partnership）制作。数据来源：Objaverse 1.0 / Sketchfab
