Lancet window in the context of "Neo-Gothic style"

Gothic Revival (also referred to as Victorian Gothic or Neo-Gothic) is an architectural movement that after a gradual build-up beginning in the second half of the 17th century became a widespread movement in the first half of the 19th century, mostly in England. Increasingly serious and learned admirers sought to revive medieval Gothic architecture, intending to complement or even supersede the neoclassical styles prevalent at the time. Gothic Revival draws upon features of medieval examples, including decorative patterns, finials, lancet windows, and hood moulds. By the middle of the 19th century, Gothic Revival had become the pre-eminent architectural style in the Western world, only to begin to fall out of fashion in the 1880s and early 1890s.

For some in England, the Gothic Revival movement had roots that were intertwined with philosophical movements associated with Catholicism and a re-awakening of high church or Anglo-Catholic belief concerned by the growth of religious nonconformism. The "Anglo-Catholic" tradition of religious belief and style became known for its intrinsic appeal in the third quarter of the 19th century. Gothic Revival architecture varied considerably in its faithfulness to both the ornamental styles and construction principles of its medieval ideal, sometimes amounting to little more than pointed window frames and touches of neo-Gothic decoration on buildings otherwise created on wholly 19th-century plans, using contemporary materials and construction methods; most notably, this involved the use of iron and, after the 1880s, steel in ways never seen in medieval exemplars.

A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.

Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, lancet windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, rose windows, emergency exit windows, stained glass windows, French windows, panel windows, double/triple-paned windows, and witch windows.
