Twin Peaks Tavern, the self-described "gay Cheers" bar in the Castro, has been recommended for landmark status by the Historic Preservation Commission, according to the Examiner.

The Commission introduced the case at a meeting on Tuesday, noting both its cultural and historical significance.

Originally an Irish pub, Twin Peaks Tavern became a popular gay bar and made history when the owners added floor-to-ceiling windows in 1972--a revolutionary decision for a gay bar at the time.

"That move represented the coming out of our community into the light instead of hiding in the shadows," said District Supervisor Scott Wiener in an interview with The Huffington Post. "Twin Peaks Tavern has enormous historical significance for the LGBT community."

The Commission mentioned the glass windows in its report, as well.

"The first known gay bar to feature full-length open plate glass windows, the Twin Peaks Tavern is a living symbol of the liberties and rights gained by the lesbian, gay, bisexual, transgendered community," wrote the Commission in its report. The Commission also noted the bar's contribution to neighborhood nightlife and community events.

However, though the recommendation may be celebrated by the city, it might not be celebrated by the property owners, who have so far remained mum.

"Landmarking a building can present additional costs and hurdles to making changes," explained Wiener. "And I'm very much of the belief that you shouldn't be landmarking a building unless the owner is supportive."

Indeed, though landmarking affects only the building and not the business, the honor would make changes to the property extremely challenging. According to Wiener, the owners have been contacted and the Commission is awaiting a response.

"We'll see what they say," said Wiener. "But regardless, Twin Peaks Tavern will always be an important asset to San Francisco."

While Twin Peaks Tavern is thriving, other historic local institutions haven't fared so well. Check out some iconic San Francisco spots in danger of closing in the slideshow below:

  • The Tonga Room

    Oh, the nine lives of the Tonga Room. Much to the Fairmont Hotel's chagrin, unyielding <a href="" target="_hplink">local</a> and <a href="" target="_hplink">national</a> support for the famous tiki restaurant in the hotel lobby have kept the band afloat at the Tonga Room, <a href="" target="_hplink">despite the Fairmont's desire to renovate</a>.

  • San Francisco Botanical Garden

    Global economic crisis tends to equal hot water for city-sponsored community programs, and the <a href="" target="_hplink">San Francisco Botanical Garden</a> is no exception. To save the garden, SFBG recently initiated a $7 entrance fee for non-residents, but the organization <a href="" target="_hplink">has also started circulating a petition and a call for help</a>.

  • The 49ers

    This deal is as good as done, and <a href="" target="_hplink">the embarrassing recent power outages</a> during a game against the Steelers may as well have been the nail in the coffin. Despite a local push to convince the team to stay, promises of a glittering new stadium in Santa Clara have been all too tempting.

  • The Castro Theatre

    We don't even want to think about it. We don't even want to utter the words. But it's no secret that the city's beloved Castro Theatre is undergoing some changes. While it doesn't seem in danger of closing anytime soon, SFist reported back in December that the theatre would be switching from a daily movie format to a live performance hall and film festival venue. Let's hope the theatre is just going through a rough patch.

  • Cafe Gratitude

    The past few months have been a whirlwind of "are they or aren't they" for Café Gratitude. First, employee lawsuits <a href="" target="_hplink">prompted the local chain to announce plans to close</a>. But a few short weeks later, the suits were "resolved." However, Cafe Gratitude is still mum on what exactly this means for the business.

  • The Balboa Theatre

    The Balboa Theatre narrowly escaped closure last year, but was saved by a last-minute partnership between former Balboa Theatre operator Gary Meyer and the San Francisco Neighborhood Theater Foundation. "It's great to save another of San Francisco's last remaining neighborhood cinemas," <a href="" target="_hplink">said SFNTF President Alfonso Felder about the agreement</a>. "We're looking forward to keeping the Balboa's marquee lit for many more years." Agreed.
