Architectural Details in Monochrome

Brief

This contest is for your monochrome photos that focus on interesting elements of architecture, such as a window, a door, a gargoyle, a pillar, a chimney, a lintel, a keystone, etc. Images can show details of the building either on the interior or exterior, capturing an individual feature of the building rather than the whole structure. Please only enter monochrome photos to highlight shape, texture, etc.
