Sightline

Typical Architectural Section of a stadium.

The illustration indicates the partially obstructed view of the front row spectators looking at the far corner flag of the adjacent touchline.

A sightline, sight line or visual axis, is a normally unobstructed line-of-sight between an intended observer (or spectator) and a stage, arena, or monument, for example. Sightlines are a particularly important consideration in theatre and stadium design, road junction layout and urban planning. In cities such as London, construction within sightlines is restricted to protect the key views of famous landmarks.
