Alas, (read at last), LOST is over. As an early fan of the show that lingered on mostly out of inertia, I couldn't agree more with the NYTimes' Mike Hale who regretted the plot's digression from mystery to mythology and that dragged its audience in senseless circles for the last few seasons. Frankly, it just got really annoying. But, what's the sense in dwelling on that. There was a time when LOST gave us secret underground hatches, geodesic domes and utopian experiments. Here's to when the epic gave us a thrill, and a few "architectural" treasures worth remembering. (Above: Radzinsky builds a scale model of the geodome on a set of Swan blueprints.)

"The LOST domes are 5/8ths truncated spheres. Geodesic spheres truncated into domes are a collision point between mathematical purity and architectural integrity. The narrative of LOST places the construction of these geodesic domes in the mid-1970s.  In the mid-1970s Buckminster Fuller was at the height of his popularity and influence.  The use of domes in LOST helps establish when the story is taking place and the sympathies of the characters that constructed them." from Synchronfile.com

The "Hatch"

And finally, one of LOST's most memorable scenes, from inside the hatch, which housed Desmond's mod living quarters and the control room.
