Solomon R. Guggenheim Museum

Judged on purpose, structure and site. The large rotunda resists the subtractive test almost entirely: the ramp is floor, gallery, circulation and structure at once; the void is light, orientation and the building’s single room; the outward lean of the wall is the ramp’s own widening. Take any of these away and the others fail. The site compels less: the building turns from the grid of Fifth Avenue and answers the park by refusing the street wall. What yields is purpose. Paintings do not need a slope, a curved wall or a shallow bay, and the form is compelled by Wright’s idea of a museum more than by the art it shows. The tower of 1992, part of the one work, is a conventional stack of galleries and offices that the form did not call for.

What can be stated, and holds: a museum can be one continuous route rather than a sequence of rooms; seeing art can be lived as movement in time, downhill, without a choice of turning; and the visitor is always in sight of the whole collection and of other visitors across the void, so that looking becomes a shared and public act. That is a way of using a public building, articulated in section. The building also disclosed, perhaps against its own intention, that a modern museum could become an event greater than what it houses, a truth the next half-century of museum building confirmed. It stands below the gate because the second disclosure is partly a failure seen as a finding, and because much of what visitors carry away is a mood, the elation of the void and the light, which ranks below a meaning.

Score: 8.3 / 10

Height is very high, and frequency is high, inside and out. Elevation comes at the entry, compressed under the low band of the ramp, then released into the void and the full height of the spiral to the glass; in looking up from the floor at the bands winding to the light; in looking down from the top of the ramp into the well, a vertigo held within a single shape; in the slow descent, the void always at the shoulder and the light changing with the hour; and outside, in the white bands stacked against the brownstones and apartment blocks of Fifth Avenue, a figure no street had prepared for. The register is exhilaration, buoyant and centripetal, never dreadful. It falls in the bays, where the art is seen close and low, and in the galleries of 1992, which are rooms like any rooms.

Score: 9.0 / 10

The archetype is built into plan and section, not applied. The spiral is the form of growth and of time: the shell, the coil, the path that returns above itself, here made the only route through the building. The stepped tower of Mesopotamia is inverted, widening toward the sky rather than narrowing to it. The domed void with light falling from its crown is the oldest cosmic room, the oculus of the Pantheon made a glass sky over a spiral rather than a sphere. Ascent and descent are both built: the elevator lifts, and the walk down is a return to the ground. Everything stays particular: this avenue, this park, a museum of modern painting. It reaches the gate and not far above it, because the cosmic room is quoted and the myth stops where the art begins.

Score: 8.6 / 10

The inheritance: the museum as palace or temple, a sequence of rooms on a symmetrical plan, as at the Metropolitan up the avenue; the modern white box of the late 1930s; and the New York street wall. The departure: no rooms, one ramp; no floors, one void; a building wider at the top than at the base, turned from the grid in curved concrete. Wright’s own path had the spiral, in the unbuilt Gordon Strong Automobile Objective of the 1920s and the ramp of the Morris shop in San Francisco, and Le Corbusier had drawn a spiral museum; none had built it as a museum at this scale. The stake was as large as any building of its decade took on: sixteen years, the client’s death, the director’s fall, the city’s resistance, and the architect dead before it opened.

Score: 9.1 / 10

Substitute a conventional museum and almost nothing this building knows survives. The form changes how the purpose is lived at every point: the visit is one walk with a beginning and an end; art is seen in sequence, in a single line of time; the whole show is visible at once across the void, so that the visitor knows where they are in it; and the crowd becomes part of what is seen. The form is the instrument of that knowledge, not its container. Held below the top because the form fights part of its purpose: walls that lean back, a floor that slopes, bays too shallow to step back from a large canvas, so that painting is shown against the building’s grain. The galleries of 1992 restore flat walls by leaving the form, and their necessity is the form’s admission.

Score: 8.8 / 10

Evidence over promise: sixty-seven years of return, and a record unusual for a building, because each exhibition remakes the rotunda and so tests it again. Artists have answered it by hanging work in the void, by filling the ramp, or by reading the spiral as the work itself. The literature runs from the quarrel over whether a museum may compete with its art, through readings of Wright’s organic architecture and of his late geometry of the circle, to histories of the commission and its politics. The questions stay open: monument or instrument, room for art or rival to it, Wright’s last word or his late manner. Held below the top because the record is shorter than that of the elder works, and because the governing idea, once grasped, is single.

Score: 8.7 / 10

The intrinsic force is a real reorganisation of the museum: the building as a single space of movement, and the museum as an architectural event in its own right. The spiral had precedents in Wright’s projects and Le Corbusier’s, which holds the force short of the top. Achieved reach is scored with intrinsic force: wide, and partly oblique. The ramped gallery itself was seldom copied, because its faults were plain. What spread was the museum as signature building, an institution known by its architecture, a line that runs through the museum building of the late century and through the foundation’s own later branches; the atrium as a public room seen from every level; and the late return of curved, free form to public building. In its field, the museum and the American public building of its decade, it moved the type.

Score: 8.9 / 10

Weighed on form, use and fabric. The form survives whole: the rotunda, the ramp, the void, the dome and the small rotunda are Wright’s and in place, and the building has outlived the conditions that made it, a collector’s patronage of non-objective painting and an architect’s late manner. The tower of 1992 changes what survives: the silhouette from the park now has a grid behind it, though the rotunda stands free in front. The use has been continuous since 1959, interrupted by the renovation of 1990 to 1992. The fabric has needed repair: the concrete cracked, and the exterior was restored in 2005 to 2008. Presence is wide, World Heritage listing among it, and earns at most a tenth. Sixty-seven years on, the figure is held a step short of the top of its range by the tower and the repaired fabric.

Score: 8.9 / 10

Judged as command of building, structure and engineering included. The command of space and light is of the first rank and load-bearing: the section, in which ramp, void and dome are one figure and the ramp’s widening gives the outer wall its lean; the light from the dome carried down the whole height. A continuous concrete helix that is at once floor and structure, cantilevered round an open well, was an achievement of form and of construction. The costs are real and charged to the work: the concrete cracked and needed major repair within fifty years; the shallow, sloping bays light and hang painting poorly; the fit of art to building was never solved within Wright’s form. The tower of 1992 is competent and plain. Command of the idea is complete; command of the building as instrument is not.

Score: 8.6 / 10

Take the two most distant elements in Wright’s part of the work: the great rotunda and the smallest detail of the floor or of a window. One law governs both, the circle and the spiral, in plan, in section, in the openings and in the pattern of the floor, and the small rotunda repeats the large at another scale and for another use. Within the rotunda the law is as strict as any building of its century obeys, and it covers structure, route, light and gallery at once. What bends it is the one work as it stands: the tower of 1992 behind is governed by a rectilinear grid clad in stone, another law, joined to the first at the back and seen with it from the park. It is a quiet second law, not a contradiction, and it holds the axis below 9.

Score: 8.6 / 10

Orders held: art and its viewing, made a route; the city, refused as a grid and answered as an avenue and a park; the natural order, in the organic form of shell and growth and in the park the building faces; the public, the crowd made visible to itself across the void; time, built as the walk itself; and, faintly, the cosmos, in the domed void under a glass sky. One section holds these together, so they are integrated. What holds the axis lowest of the twelve is what is absent: the household, labour, the state, the sacred except as an old form, and death. A museum holds the viewing of art and the city’s public at leisure, and the figure describes the form.
