Anyone who visits one of Connecticut’s art, cultural, science and historical attractions is supporting a very important industry — one that generates $14.7 billion in annual revenue.

It’s Connecticut’s thriving tourism industry, explains Randy Fiveash, director of the state’s Office of Tourism in a recent chat. Fiveash said the state’s plethora of tourism offerings is extraordinary — and wants Connecticut residents to be able to visit them for free or reduced admission.

“Connecticut started this program — Open House Day — 14 years ago to encourage residents to explore their own backyard” and to be proud of all its diverse attractions for both adults and children, he said.

The annual event is always on the second Saturday of June — this year on June 9. All attractions are invited to participate; this year about 230 across the state will welcome Connecticut residents with free admission or other special promotions. A variety of facilities, such as art museums, kids’ centers and historical homes, are giving residents the impetus to finally visit attraction they’ve been meaning to tour.
