Crews are preparing to reinstall the first of four sets of stained glass windows in a $3 million restoration project at the South Dakota state Capitol.
The panels will be returned Thursday to the barrel vault above the main marble staircase. Thirty of the 90 panels in the skylight were cleaned in place because they aged better than others.
The crews from Conrad Schmitt Studios have travelled back and forth several times between New Berlin, Wisconsin and Pierre.
Glass panels are being cleaned and re-leaded in Wisconsin. Time and gravity has strained the 100-year-old glass.
Stained glass in the House and Senate chambers and the domed rotunda are still being cleaned. They will return to the Capitol in September.
The entire project will be completed before the state's 125th anniversary.
