Millennium Park in Chicago, Illinois.
"It was clearly a game-changer, not only for Chicago and the real estate that surrounds the park, but for its influence on cities everywhere," says Carol Coletta, the VP of Community and National Initiatives for the John S. and James L. Knight Foundation.
Coletta manages millions of dollars annually in grants for city design, and says Millennium Park is the ideal public space. Intended to celebrate the second millennium, the 25-acre park hosts public art and events.
"Lurie Garden, tucked in the park’s southeast corner, is one of my favorite places in the world that somehow manages to remain deeply calming in the midst of the chaos of the larger park," she says.
Spruce Street Harbor Park in Philadelphia, Pennsylvania.
Bordering an urban beach, Spruce Street Harbor Park features colorful lights at night and hammocks for lounging.
It "was intended to be a temporary intervention — really a desperate move for a very tough location separated from Philadelphia’s Old City by a wide and busy road," Coletta explains. "But it keeps going and going because people keep coming and coming. It is a simple, loving intervention whose design elements have been widely copied."
The central square in Seaside, Florida.
Building a new residential housing development that actually feels like a small town is almost impossible, says Steve Mouzon, the founder of Mouzon Design.
But the founder and developer of Seaside, Florida did just that, using public space to foster a new independent, tight-knit community.
"The developer had the audacity to build a town square, with a post office, a grocery, a bookstore, and a collection of other restaurants and shops with apartments above," Mouzon explains. "Never mind that the post office wasn’t a sanctioned US Post Office, but rather ganged mailboxes installed inside a tiny civic building. Because the mailboxes wore civic clothing, people behaved in a civic way. And even though Seaside has never been incorporated as a town, people nonetheless behave in neighborly ways."
The streets of New Orleans, Louisiana.
New Orleans' street design is exceptional because they're incredibly walkable, says Eric Kronberg, the principal of design and architecture firm Kronberg Wall.
"I had the really good luck to choose Tulane School of Architecture in New Orleans for college," Kronberg explains. "I’ve spent the last twenty years since graduation returning to the city. I measure, photograph, and observe all the little things that contribute to the city on each visit. These typically unnoticed things like street width, block length, sidewalk conditions, relationship of buildings to the street, all represent dense, walkable urbanism at a human scale."
Prospect Park in Brooklyn, New York.
"It is so many things to so many people and really serves all of the communities around it," says Julie Ember, associate director of design at New York's Bryant Park Corporation and 34th Street Partnership, of Brooklyn's largest park.
"It is simultaneously a beautiful escape into nature while being fully representative of the city and the human touch. It is a great balance of open-ended space and programmed space; and maybe most importantly, its landscape is really varied and interesting and never fails to surprise me."
Hosier Lane in Melbourne, Australia.
Hosier Lane is "a graffiti laneway in Melbourne’s city center that effectively brought about the gentrification of street art and legitimized its validity in the city’s modern culture," says Dale Bowerman, who worked as an urban planner for the city of Melbourne. "Once upon a time, [it was] home to a Banksy artwork, which was accidentally painted over by Council workers."
La Trobe Reading Room at the State Library in Melbourne, Australia.
"The [reading room] dome was the largest of its type in the world on completion" in 1854, Bowerman says. It is "a place that citizens can always rely on for peace, quiet, solitude, and reflection."
The octagonal space was designed to hold over a million books and up to 600 readers, making it a welcoming space for visitors.
Strietzelmarkt in Dresden, Germany.
Strietzelmarkt is “the oldest Christmas Market in Germany. Booths fill the square, but also run for miles north from the Hauptbahnhof through the Strietzelmarkt, across the river, to Albertplatz,” says Craig Toocheck, a designer at the National Association of City Transportation Officials in New York City.
He adds that it serves as a shared space, where people can congregate and hang out.
Point State Park Promenades in Pittsburgh, Pennsylvania.
Pittsburgh's waterfront promenades were "once the site of factories, made a park in the '60s," Toocheck explains.
The area was renovated in 2011, and is now "home to Pittsburgh's iconic fountain and lovely riverfront promenades," as well as a smooth pathway with beautiful views for cyclists and walkers.
The streets of Borehamwood, England.
After the town of Borehamwood, England banned cars from certain streets in its center, it felt like a different place, Kurland says.
"It is not a particularly aesthetically beautiful place, but I saw how it transformed from a … traffic-dominated road, stopping the town from having a functioning center, to a calmed, more pedestrian friendly, smooth flowing, busy but not interesting high street," she says.
Trafalgar Square in London, England.
Since the 13th century, London's Trafalgar Square has been used for gatherings and political demonstrations, including Bloody Sunday, the first Aldermaston March, anti-war protests, and campaigns against climate change.
Over time, the city has made tweaks to the Square's design, making it more pedestrian-friendly, Kurland says.
"Trafalgar Square was a very influential scheme for me — seeing what could actually be done, changed, with simple things like new steps ... and removing a small element of trafficked space," she says. "The argument over whether it would cause gridlock in central London or not was very interesting, and opened up a whole new set of questions for me."
Los Bosques de Palermo in Buenos Aires, Argentina.
Los Bosques de Palermo has many different areas and attractions for Buenos Aires residents, including sports fields, groves, lakes, a zoo, and rose gardens.
Ignacio Ciocchini, VP of design for the Bryant Park Corporation and 34th Street Partnership, grew up in the Palermo neighborhood, and says he used the park all the time. "The large football [soccer] fields across my house where we went every day and the town square in front of the church where we met up with friends in the evening were part of my daily life," he says.
