Dallas City Hall has landed on Preservation Texas’ 2026 list of the state’s most endangered historic places, drawing renewed attention to the ongoing debate over the future of the iconic downtown building.
The nonprofit organization announced the list Tuesday, placing the Brutalist-style structure designed by renowned architect I.M. Pei among six threatened sites across Texas. Completed in 1978, the inverted pyramid-style building at 1500 Marilla Street has become a symbol of modern Dallas architecture and civic life.
Preservation Texas highlighted concerns that city leaders are seriously considering relocating operations and potentially demolishing the structure to make way for redevelopment. The group noted that despite deferred maintenance issues, the building remains structurally sound and capable of continued use. It has served as a backdrop for public meetings, protests, and community events for nearly five decades.
The designation aims to raise public awareness and mobilize support for preservation efforts. Preservation advocates argue that losing the landmark would erase an important chapter of Texas architectural history, particularly as Brutalist buildings from this era face increasing threats nationwide.
The listing comes amid active discussions at Dallas City Hall. Council members have directed staff to study both full relocation options and phased repair plans, including a more affordable 10-year approach versus a previously proposed $1 billion accelerated repair program. The debate also intersects with broader downtown planning, including potential sites for a new Dallas Mavericks arena.
Dallas City Hall joins other notable entries on this year’s list, such as Houston’s Garden Oaks Theater and Austin’s Barton Springs Bridge.
