St. Patrick's Cathedral is embarking on a multimillion-dollar renovation.
The $175 million facelift of the Fifth Avenue church is slated to begin at the end of April and last at least two years. The 2,200-seat white marble cathedral opened in 1879.
Cardinal Timothy Dolan is expected to announce the renovation Saturday.
Scaffolding and netting is expected to go up inside and outside the church.
The work will include replacing crumbling marble blocks and refitting stained-glass windows from the 1870s. It will be done every day from 7 a.m. to 3:30 p.m., stopping for daily Masses.
Funeral Masses for Babe Ruth and Robert F. Kennedy were held at St. Patrick's. The cathedral gets more than 5.5 million visitors a year.
