HERITAGE SQUARE FOUNDATION

What HERITAGE SQUARE FOUNDATION does

Heritage Square Foundation is a 501(c)-style nonprofit founded in 1980 and headquartered at 113 N 6th Street in Phoenix, Arizona, operating under the brand The Square PHX. The organization preserves and programs Heritage & Science Park, a cultural complex on Block 14 of the original Phoenix townsite comprising late 19th- and early 20th-century historic buildings, anchored by the iconic Rosson House Museum, the Lath House Pavilion, and the Memorial Rose Garden. The site is acknowledged as the traditional territory of the O'Odham and Piipaash peoples.

The Foundation operates a diversified portfolio of cultural and educational offerings: guided tours of the Rosson House (standard, flashlight, happy hour, séances/spiritualism, private group, and field trip formats), a self-guided Block 14 audio tour, annual signature events (Faire @ the Square, Galaxy STEM Fest, the upcoming Sounds of Suffrage for America 250 theatrical event in partnership with Arizona Curriculum Theater on August 29, 2026), recurring educational programs (Teen STEM Café, Block 14 Book Club, Family Fun @ the Square), online learning content via History @ Home, venue rentals for private events, and an on-site Museum Store. The organization serves a broad audience including general visitors, families, school groups, event organizers, and tourists in the Phoenix metropolitan area.

Revenue is generated through six streams: museum tour ticket sales (e.g., $12 summer special), annual memberships (starting at $40), individual donations, venue rentals, museum store retail, and corporate sponsorships. The Foundation also receives institutional grant funding from Arizona Commission on the Arts, Arizona Humanities, and the City of Phoenix Arts & Culture program. Marketing is conducted through a multi-channel approach spanning a WordPress website with SimpleTix-powered online ticketing, Facebook, Instagram, TikTok, YouTube, email newsletter, and signature in-person festivals. Operations are constrained to weekend museum hours (Friday through Sunday), and the team consists of 1-10 employees.
