A pneumatically inflatable structure includes first and second parallel spaced apart pneumatic end support tubes and at least two opposed pairs of bowed criss-crossed pneumatic bracing tubes and an arched canopy extending over the support tubes and bracing tubes. Each of the end support tubes has first and second opposed ends each mountable to a base surface wherein each of the end support tubes forms a vertical arch having an apex when the structure is erect. The pneumatic bracing tubes have first and second ends wherein each of the first ends of the bracing tubes are secured to one of the first or second ends of one of the first or second end support tubes. Each of the second ends of the pneumatic bracing tubes are securable to substantially the apex or thereabouts of an opposed tube of the first or second end support tubes.
