Roy and Clara Miller collected rocks and shells during their 1930s-1960s travels and transformed them into miniature Lucas buildings. The stand-alone towers they made from slag glass and barite roses. Visitors stopped often to see this roadside attraction, but after Roy's and Clara's deaths the miniatures were moved to Hays in 1969. Thanks to passionate efforts, these works of art came home to Lucas in 2013. In a park-like setting, the miniatures can be admired from behind the fence.
