It’s finally that time of year: Everybody’s favorite mid-March holiday is upon us. No, not St. Patrick’s Day, or the Ides of March (only beloved by the guys who killed Julius Caesar, really); we’re talking about Pi Day. 

Is it rational? No, of course not. But hey, at least it doesn’t go on forever… And neither does this list our staff put together of beloved circular sights around Seattle. But we’ll admit, when you start thinking about all our favorite circles, it’s hard to stop.

Anyway, without pi we wouldn’t be able to tell you that the area of a 13” pizza from Pagliacci is approximately 132.73 square inches. (The radius of a Dick's hamburger bun was not readily available for calculation purposes at the time of publication.) And without pi, the architects, designers, and craftspeople responsible for the following favorites would have had a heck of a hard time:

• The Black Sun sculpture by Isamu Noguchi at Volunteer Park
• The parking lot ramps at Sea-Tac
• The Metropolitan Market cookie (Not the new peanut butter one)
• The roof of the Tacoma Dome
• The top of the Space Needle
• The International Fountain underneath the Space Needle
• A Dick’s Deluxe
• A Pagliacci Pizza
• Apples (Washington grown, of course)
• Hum bow from Mee Sum at Pike Place (though the best flavor, beef curry, is oblong)
• The Mariners’ compass rose logo. 
• Any of the cool labyrinths painted around town (we’re especially partial to the ones at Seattle Center and St. Mark’s Cathedral).
• All of the roundabouts that keep our neighborhoods safer for pedestrians.
• The ladybug Wallingford residents painted at 49th and Burke where there should be a roundabout. 
• Flour Box doughnuts.
• The lazy Susans on the round tables at Jade Garden.
• Local beer in a can, bottle, or pint glass. 
• A cup of coffee from your favorite neighborhood shop. 
• The Seattle manhole covers with the city maps imprinted on them. 
• The Amazon Spheres. Hahaha just kidding. 
• The Great Wheel, begrudgingly.
• The Westin towers.
• The yellow eyes staring out at you from that one house off I-5.
