A Dubuque construction group plans to purchase several buildings at a well-known area religious site to turn into an active senior living community. Dominican Sisters of Sinsinawa named Dubuque-based Tricon Construction Group as the selected buyer for several buildings at Sinsinawa Mound, which has been the home of the congregation for more than 175 years. Tricon plans to renovate the buildings at the site in Grant County into an active senior living community for adults 55 and older and event center. Preliminary plans call for around 115 apartments, though the final number could change. Sinsinawa leadership started seriously considering a partial sale of the buildings more than five years ago after a continued decline in membership since the 1960s.
