Stone arch: no columns or moldings

A stone arch: no columns or moldings. The opening between rooms is a semi-circular or slightly flattened stone arch, with individual arch stones visible and a slightly larger keystone in the center; the sides of the arch rest directly on the wall, with no columns or moldings. Avoid: using square door openings with moldings, making the arch a veneer of fake stone, adding columns and intricate decorations, making the arch proportion too tall.

一道石砌的拱。房間之間的開口是半圓或稍扁的石砌拱,拱石一塊一塊看得出來,中央有一塊稍大的拱心石;拱的兩側直接落在牆上,沒有柱也沒有線腳。避免:使用方正的門洞加線板、把拱做成貼皮的假石、加入柱式與繁複的裝飾、讓拱的比例過於高聳。
