In the 1990s Denison began attracting artists to its Main Street district. Artists settled into many of the 19th century buildings along Main Street and converted them into art galleries and artists studios. Denison now is home to the work of many artists with local, regional, and national acclaim. The Denison Arts Council promotes two Fine Art Tours each year to showcase the growing talent of the area. Many other historic buildings now house loft living spaces and specialty shops. Denison arts have been featured in Texas Highways Magazine , Texas Monthly , Art Talk and others.
