Just how long ago was it? One of those nagging questions. In this case, I was wondering when the last time I’d been to downtown Detroit. I couldn’t remember until I looked it up.

Right. Seventeen years. This time we arrived on Saturday morning. After visiting St. Joseph Shrine, we repaired to Campus Martius Park, which counts as a green spot in the heart of downtown Detroit, and which was still being developed the last time I was in the area.

When I went looking for information about the history of the park, I was amused that the Downtown Detroit Partnership hadn’t gotten around to writing anything. And yet the dummy Latin evokes the origin of the original Campus Martius, which even dummy students of Latin (as I was) know was the gathering place in the early Roman Republic for legions before they went out to kick barbarian butt, and later was home of the Pantheon.

The Michigan Territory borrowed the name not directly from Rome, it seems, but a place in Ohio. In the 19th century, citizens gathered at the Detroit Campus Martius in war and peace, but the spot was neglected in the 20th century, becoming mostly just a place through which cars passed.

In the 21st century, Campus Martius was reinvented as a park to help bring new life to downtown. It’s a fine bit of urban planning. Why do I think that? Because it features not only things to do and look at, but chairs with actual backs on which it’s actually fairly comfortable to sit during the warm months. How many cities don’t understand how important that is, perhaps worried that the homeless might find someplace to sit? Many.

The park also includes a cafe, a small stage, a bit of green space, a fountain, a sandy “beach” in summer and an ice rink in winter, a view of impressive buildings, and an embedded zero milestone, which is called the Point of Origin.

As I understand it, all of the Detroit area’s mile roads, such as the famed 8 Mile Road, measure from this point.

The Michigan Soldiers and Sailors Monument is also part of Campus Martius Park, which seems reasonable.

“The Soldiers and Sailors Monument is among Detroit’s oldest pieces of public art and was one of the first monuments to honor Civil War veterans in the United States,” Historic Detroit says. “It was announced by Gov. Austin Blair in 1865 that money would be collected to erect a tribute to Michigan’s soldiers killed in battle. Detroit, being the largest city, won the right to the monument.

“The cornerstone for the monument was laid July 4, 1867, but not in Campus Martius, where the monument stands today… a special committee of the [city] council resolved in September 1871 that the best place for the monument was the open square in front of City Hall.

“The bronze and granite sculpture was formally unveiled on April 9, 1872, though some of its statues were not added until July 18, 1881… The Classical Revival monument stands more than 60 feet tall and was sculpted by Randolph Rogers, an Ann Arbor native who studied at the Academy of St. Mark in Florence, Italy, under Lorenzo Bartolini.”

In 2003, the monument was moved about 150 feet to the south as part of the creation of Campus Martius Park. According to carving in the plinth, a time capsule was entombed there as well in 2004, to be opened on July 23, 2104.

An array of buildings.

In the foreground, the Qube, previously known as the Chase Tower, another Albert Kahn work, but from a later year: 1959. Behind it to the left is the magnificent Guardian Building, more about which later, and the Penobscot Building, another 1920s masterpiece.

One of the more sizable buildings towering over the park is the 985,000-square-foot One Campus Martius, a 2003 development of Bedrock Detroit, the real estate arm of billionaire Dan Gilbert’s empire. Michigander Gilbert has developed, and probably more importantly, redeveloped a lot of properties in Detroit.

Poised at the entrance of One Campus Martius is “Waiting,” a mildly unnerving 17-foot bronze by Brooklyn-based artist Brian Donnelly, also known as Kaws.

“ ‘Waiting’ is another high-profile acquisition by real estate magnate Gilbert and his wife, who purchased the statue for their growing Detroit Art Collection — a wide-ranging portfolio of immersive installations and public art that span Bedrock’s real estate portfolio downtown,” notes the Detroit Free Press.

Campus Martius Park was just the beginning for us that morning. We’d come for a 10 o’clock walking tour of downtown Detroit lead by Preservation Detroit, and that’s where it started; more about that soon.
