The people of Cyra were nomadic herders. Therefore, they did not possess many material goods that were heavy or bulky as those could not easily be moved from location to location. Although they did have some semipermanent dwellings where they settled seasonally, they did not create or own large works of art like other kingdoms.
Therefore, their 'architecture' consisted largely of tents for their nomadic lifestyle and larger yurts in their semipermanent dwelling areas. And there were no statues, paintings, or sculptures in their artistic repertoire.
That's not to say their dwellings weren't beautiful or cozy. Quite the contrary. In fact, they were quite elegant and elaborate and surprisingly comfortable. And despite their lack of large-scale artworks, they did have amazing textiles, pottery, baskets, glassware, metal work, and jewelry.
