Monumental

Does "monumental" in the following contexts mean "memorial", "huge" or "fascinating"?

Context:

1. As his maquettes for the work make clear, Oldenburg devised Lipstick (Ascending) as a work that could be altered at will with the use of interchangeable parts—or, as Oldenburg put it, “stages of extension”—involving its uppermost, priapic element. The pedestal-like lower portion of the work consists of a form that references the gears, base, and track of a tank. Oldenburg’s military reference here is clear. The final element, a vertical column
painted to resemble a tube of red lipstick, was erected on a short platform placed directly on top of the track or base of the work, which also functioned as a stage for speakers. The rigid columnar element could be replaced with a similar vertical structure that Oldenburg crowned with an inflatable, and collapsible, red balloon. The columnar element could then be completely vertical and rigid or be in various stages of flaccidity or deflation. This
collapsible component of Lipstick (Ascending) relates to other works by Oldenburg, where he realized everyday objects as “soft sculptures” made of canvas, such as Soft Typewriter (1963). It is also part of the series of large-scale public sculptures Oldenburg produced in the late 1960s, which expanded everyday objects, such as a women’s lipstick, into gigantic, monumental forms.

2. Painted on a large scale and with dry acrylic brushstrokes on linen, the size and medium that he favored throughout his oeuvre, Golub’s work intimated the linear qualities of the most dramatic and monumental sculptural reliefs of ancient Greece, and the writhing surface of other representations of bodily conflict, such as Pollaiuolo’s Renaissance engraving Battle of Naked Men
