One of only two Byzantine Catholic congregations in Denver is looking to upgrade. Holy Protection of the Mother of God has listed its existing church building at 1201 S. Elizabeth St. with an asking price of $1.1 million. That’s $435 a square foot for the 2,600-square-foot structure, which listing agent Matt Harper said a buyer could use as a day care or residence. “It’s a very interesting architectural building,” Harper said.
