One of the first artists to develop environmental site-specific sculpture in the early 1970s, Tacha has won over fifty competitions for permanent public art commissions, of which nearly forty have been executed throughout the U.S. One of these public works was a two-acre sculptural landscape in downtown Philadelphia, Pennsylvania entitled Connections within Matthias Baldwin Park.

She produced a body of textual and photographic conceptual works and poetic studies, many of which were published as artist's books.

In 1989, a retrospective of more than 100 of Tacha's sculptures, drawings and conceptual photographic pieces was held at the High Museum of Art in Atlanta.

It included large color photographs of her executed commissions and was accompanied by a fully illustrated catalog, Athena Tacha: Public Works, 1970-88 (introductory essay by John and Catherine Howett).

The same year, she had an exhibition of new work, over 50 sculptures and drawings, as well as two large temporary installations, at the Cleveland Center for Contemporary Art, also accompanied by a richly illustrated catalog (with an essay by Thalia Gouma-Peterson).

Her most recent museum solo show, Small Wonders: New Sculpture and Photoworks at the American University's Katzen Arts Center, Washington, DC, 2006, had a fully illustrated catalog with essays by Anne Ellegood and Brenda Brown (reinstalled in New York at Kouros Gallery in 2007).

It presents for the first time all aspects of Tacha's art—from large outdoor commissions, to "body sculptures" and photoworks, to conceptual art and films—with a bilingual catalog (164 pp., 113 color illustrations).
