The mark consists of a portion of a building exterior and roof. The roof is red-orange in color. The left portion of the roof is gabled, morphing into a frusto-conical right portion of the roof curving around the right side of the building. Both the gabled and frusto-conical roof portions are presented as planar surface roof portions with upwardly extending converging runners on the truncated cone portion of the roof and with upwardly extending parallel runners on the gabled portion of the roof. Ornamental, decorative snow guard-like parts are close to the lower edges of the gabled and frusto-conical portions of the roof. The frusto-conical portion of the roof terminates on the right side at a rectangular masonry tower extending above the roof. On the front of the tower is a tan lintel presented as a horizontal member and a vertical member with the vertical member extending upwards from the midpoint of the horizontal member. Above the vertical member is the word "citadel" in black with a star representing the dot on the "i". An abstract design to the left of the word "citadel" consists of a gold oval separated from a generally triangular shape having curved sides, with the lower portion of the triangular shape being blue and the upper portion being dark red. Applicant does not claim the matter shown in broken lines in the drawing-namely, the windows, the window muntins, the portico, the roof support columns, nor the shapes of the individual masonry stones - as features of the mark.
