📍 Local Insights
🏫 A Historic Schoolhouse: The venue is the historic Cantril School Building at 312 Cantril St — not to be confused with the Cantril House assisted-living residence elsewhere on the same street.
🖼️ Cantril Gallery: Exhibitions rotate throughout the year and openings (TAP Talks) are typically free and open to the public — a low-key way to meet local artists.
🎟️ Classes Fill Up: TAP releases its catalog in six-month blocks (150+ offerings). Register online at triartsproject.org rather than dropping in.
🤝 Community Roots: TAP partners with the Castle Rock Artist Alliance and is supported by local funders, making it a genuine community art hub rather than a commercial gallery.
