![Big Reveal: The 2026 Chicago 7 Most Endangered Buildings
Join Ward Miller, The Richard H. Driehaus Executive Director of Preservation Chicago, in the annual unveiling of the 2026 “Chicago 7” Most Endangered Buildings. Hear all about these local treasures— their colorful histories, architectural and cultural significance, demolition threats, and what can be done to protect them.
The 2026 Chicago 7 Most Endangered List
1. The Art Institute of Chicago: Stock Exchange Trading Room & McKinlock Court [21:10]
The Threat: The Art Institute is planning a massive new expansion. The proposed footprint initially targeted McKinlock Court (the beloved interior garden courtyard) and threatens Adler & Sullivans historic Chicago Stock Exchange Trading Room (which was saved and meticulously reconstructed inside the museum in the 1970s) [22:14, 27:31].
The Alternative: Preservation Chicago is advocating for the museum to expand over the two below-grade railroad trenches running to the north and south of the complex, healing those infrastructure scars just as Millennium Park did [23:10, 28:43].
2. Chicago Bridges & Tender Houses (Thematic District) [27:31]
The Threat: Chicago holds the largest collection of historic bascule bridges in the nation, but many are suffering from extreme deferred maintenance, structural deterioration, and rust [28:24]. The historic Chicago Avenue Bridge tender house is currently facing demolition [28:12].
The Goal: Pushing CDOT and IDOT to proactively invest in, clean, and properly landmark these iconic neighborhood gateways [27:59].
3. St. Mary’s Church (Riverdale) [29:51]
The Significance: Located on the far south side, this 1957 church campus (dating back to an 1890s congregation) is deeply tied to the youth of Pope Leo XIV—the first American pope [30:19].
The Threat: Closed by the Archdiocese in 2011, the five-building campus has faced severe neglect, water infiltration, and roof collapse [30:50, 31:45]. Current ownership wants to preserve it, but requires widespread support to stabilize the structures [32:26].
4. Chicago Labor Union Halls [33:38]
The Significance: A thematic focus on historic post-war and mid-century modern union buildings celebrating Chicagos profound labor history [33:47]. Featured spaces included the Workers United Hall [33:59], Painters District Council [34:26], Plumbers Union Hall [34:55], and Teamsters 710 [35:14].
The Immediate Risk: The Amalgamated Meat Cutters building at Sheridan and Diversey is actively facing a high-rise redevelopment proposal that would demolish the structure, saving only two exterior sculptures [35:32, 36:11].
5. Chicago Loop Synagogue [37:53]
The Threat: Designed by Loebl, Schlossman & Bennett in 1957, this architectural gem features a spectacular, massive stained-glass wall by Abraham Rattner [37:59, 39:07]. Due to shifts in the downtown population, membership has dwindled from tens of thousands down to fewer than 500 [38:23]. Preservation Chicago wants to secure landmark status to safeguard it as the La Salle Street corridor transitions to more residential use [40:23].
6. South Park Terrace [40:54]
The Significance: A unique 1905 residential courtyard complex at 61st and MLK Drive designed by Harry Hale Waterman, who worked under J.L. Silsby alongside Frank Lloyd Wright [40:54, 41:09].
The Threat: The building has suffered from severe mismanagement and recent fire damage [41:26]. The city has ordered portions cleared, leaving it highly vulnerable to demolition unless the CHA or affordable housing developers step in [41:31, 42:09].
7. The Yukon Building [43:04]
The Significance: An incredibly rare, ultra-modern 1898 glass-and-metal taxpayer building at Clark and Van Buren, designed by legendary firm Holabird & Roche [43:04, 43:46]. It stands as one of the last remaining physical links to Chicagos Old Chinatown hub before the community moved south in the 1920s [44:23]. It is highly vulnerable to being cleared for high-density downtown development [46:23].
+1. St. Mark Roman Catholic Church (Humboldt Park) [46:32]
The Threat: A soaring, plastic mid-century modern concrete-and-brick masterpiece built in 1963 by Barry & Kay [46:38]. Serving as a longtime anchor for the neighborhoods Puerto Rican and Latinx community, the church was recently closed and the campus is up for sale [46:46, 47:00]. Advocates want to see it converted into a community center or library branch rather than private residential lofts [48:05, 54:53].

![Why Does This Classic Chicago Skyscraper Look Like a Giant Champagne Bottle?
Does Chicago actually have a skyscraper designed to look exactly like a massive, luxurious bottle of champagne? In this fun and informative installment of Docent Talks, the Chicago Architecture Center dives deep into the archives to separate architectural myth from history, uncovering the true story behind one of Michigan Avenues most striking Art Deco masterpieces. Read the highlights below:
The Birth of an Icon (1929) [00:10]
The spectacular Carbide & Carbon Building opened its doors on North Michigan Avenue in 1929 [00:10]. It was commissioned by the New York-based Union Carbide and Carbon Corporation [00:15] and designed by the Burnham Brothers—the talented sons of legendary Chicago urban planner and architect Daniel Burnham [00:22].
Uncovering the 1928 Business Diary [00:27]
For decades, locals whispered that the building’s unique aesthetic was a cheeky nod to alcohol during the height of Prohibition. The truth was finally uncovered in the personal business diary of Daniel Burnham Jr. [00:27]. An entry dated March 16, 1928, details a meeting with a Carbide executive who explicitly requested the towers unique palette [00:30].
A Black-Green Like an Old Champagne Bottle [00:53]
The executive wanted a striking look inspired by New Yorks black-and-gold American Radiator Building [00:45], but specifically requested the body of the Chicago tower to be a black green like the color in an old champagne bottle. [00:53] To achieve this gorgeous look, the architects used:
The Base: Deep, polished black granite cladding across the bottom three stories [01:01].
The Ornamentation: Dark green terra cotta panels climbing the body of the tower.
The Cap: Brilliant, brilliant accents detailed in a thin layer of genuine 24-karat gold leaf across the top three stories [01:08].
The Ultimate Prohibition Mystery [01:14]
While the executives diary entry proves the champagne color connection is 100% true, it leaves one tantalizing mystery unsolved: did the architects intentionally design the gold top and dark bottom to mimic the foil top and label of a champagne bottle? [01:14] The diary doesnt say, leaving a bit of romantic mystery hanging over the skyline.
A Modern Day Landmark [01:44]
Originally built as a brilliant form of visual advertising to command attention from blocks away [01:37], this Art Deco marvel continues to stun passersby today. While it is now home to the Pendry Chicago, a luxury boutique hotel [01:44], it proudly keeps its historic status as the most effervescent building on the Chicago skyline [01:51].
