A Denver theater company has listed its Golden Triangle converted church for sale, months after the company reported being in a “financial crisis.” Constant upkeep on the nearly 130-year-old building at 1080 Acoma St. has become too much to manage for Curious Theatre Co., according to Jeannene Bragg, the nonprofit’s managing director. “The building is our biggest asset, but it is also our biggest liability,” she said. Bragg said Curious spends nearly $10,000 per month on the mortgage and utilities, and then has to deal with the additional expenses of repairs and renovations. The listing comes months after Curious launched a public emergency fundraising campaign in March, saying it needed to raise $250,000 by July.
