Gallery ridges are about 23.2 m front and 23.5 m rear, curved garden peristyle terrace 13.4-14 m, principal corner roof peaks about 28.4-29 m with ornament below 33 m. Roof planes, eaves and pavilion outlines are inferred from these returns and reviewed photographs.","Selected Commons Chabe01 Petit Palais Paris2.jpg gives the west colonnade, paired monumental Corinthian columns, giant portal arch, slate dome and corner pavilion silhouettes. Guilhem Vellut Entrance @ Petit Palais and Dome @ Garden give the stepped archivolts, circular dome oculi, ribs and open lantern. Sigoise Cour intérieur et jardin du Petit-Palais 04.jpg gives the open paired granite garden columns, flat entablature, lower balustraded terrace and higher pilastered gallery walls. David.Monniaux oblique aerial gives coarse evidence for the open court and pitched perimeter roofs, not measurements.","The museum official history https://www.petitpalais.paris.fr/explorer/le-petit-palais/lhistoire-du-petit-palais explicitly identifies four oculi at the entrance rotunda roof base. Four cardinal primary hoods are retained in both LODs.","Central drum radius about 10 m and authored dome profile follow radial IGN quantiles: 23.3 m at radius 10, 28.3 at radius 8, 30.6 at radius 6, 32.1 at radius 4, 33.5 at radius 2.5. Narrow open lantern, cupola and 42 m finial remain in the measured central high cluster.","Window/door/oculus panels are attached to real walls and hoods. Front portico and curved paired-column garden peristyle are genuine air spaces below their stone roofs. Sculpture, Corinthian capital bells, urns and gold grille are original abstract geometry; no inscriptions, heraldry or individual carvings are copied. Both authored LODs preserve court, open colonnades, portal and roof hierarchy. Low repeats fewer garden column pairs and shifts the shafts roughly 1 m within the peristyle band, keeping air between the central pair while floor and roof are clipped to the original mapped garden niches."],"source":{"url":"/objects/c26fc0ca846c4f9726fba213d409c38f7f3484b7bc30e3c83c84f957fb3095f5/source.blend.gz","bytes":668162,"sha256":"c26fc0ca846c4f9726fba213d409c38f7f3484b7bc30e3c83c84f957fb3095f5"},"spatialSource":{"url":"/objects/289138663f12ae91bc260b5771672bc4a89901b605097a8f1c1e1ddd0d47fc86/spatial-source.json","bytes":21897,"sha256":"289138663f12ae91bc260b5771672bc4a89901b605097a8f1c1e1ddd0d47fc86"},"preview":{"url":"/objects/a74f3448f6f43debc490696ae7b06978cfb3698721124dcf8998a8dd48e29e14/preview.webp","bytes":13608,"sha256":"a74f3448f6f43debc490696ae7b06978cfb3698721124dcf8998a8dd48e29e14"},"previewDirection":[-1.8,0.8,1],"revision":"98a71360e183373226fdc23380de67f5542a276b3753c3741816bfcc98bb61e3","publicationRevision":"4fceded549244023c6b73e76f9ab2efd9d4c2f03ed46070bd4a322de1823311d","bounds":[2.3143339,48.8654594,2.3156049,48.866628],"approved":false,"materialLibrary":{"schemaVersion":1,"sha256":"7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd","url":"/materials/7afc40cf0b82b7c3c054f287817be2a37e52192aa734f187f8b20ee3277187dd.json"},"metadata":"/assets/petit-palais/4fceded549244023c6b73e76f9ab2efd9d4c2f03ed46070bd4a322de1823311d/asset.json","validation":"/assets/petit-palais/4fceded549244023c6b73e76f9ab2efd9d4c2f03ed46070bd4a322de1823311d/validation.json"}
