At the Gates was an extreme Metal band from Gothenburg, Sweden, and a major progenitor of the Gothenburg Death Metal sound, active from 1990 to 1996. Although starting as a Death Metal band, At the Gates is probably best known for their 1995 album Slaughter of the Soul, which is the most melodic record they did.
At the Gates has used two logos over the time. The most popular one might be the one depicted on the Slaughter of the Soul cover, but the most interesting and stylistically impressive one is the older logo you can see on the left, that for the first time appeared on their debut EP Gardens of Grief (in a less balanced appearance).
This logo is based on a centuries old artistic system established in the French early-Gothic period (c. 1140-1200) and later in the English period of Gothic architecture (1200-1275). This special motif is the lancet arch, mostly used for windows in Gothic architecture, as the integration of light was an important aspect in that period.
Lancet archs are typically defined as two-centered arches whose radii are larger than the arch’s span. Lancet openings are often grouped, usually as a cluster of three (or five). This logo integrates the band name into three archs, while connecting them.
