World's Wonder View Tower, Tourist attraction and observation tower in Genoa, US.

World's Wonder View Tower is a 65-foot (20 m) square tower in Genoa, Colorado, built of stone and painted red, its paint now peeling. An enclosed observation deck with rectangular windows projects on three sides midway up, below a smaller glazed top section with a dark metal railing; a sign above the deck reads "SEE 5 STATES". A lower stone addition with a corrugated metal shed stands at its left base, and a curved concrete wall with faded red graffiti abuts the tower on the right.

C.W. Gregory, called Colorado's P. T. Barnum, and his partner Myrtle Le Bow built the tower in the mid-1920s. In 1934 the site was confirmed as the highest point between New York and Denver. The promoters claimed six states were visible from the top. The tower closed after the owner's death and its contents were auctioned on September 20, 2014; it reopened in 2026 after renovation.
