There's no coffee shop to duck into on a Tuesday morning in Mass Ave Heights. No corner market, no restaurant row, no bench outside a bakery where you'd run into a neighbor. The wedge of land between Massachusetts Avenue and Garfield Street holds some of the most private real estate in Washington, but it holds almost nothing you could call a business. For residents here, the walk is the neighborhood's public life, and nearly all of that walk runs through land owned by the Washington National Cathedral.
That arrangement has worked for a century because the Cathedral's grounds have stayed reliably open. This year, a piece of them didn't.
A Neighborhood Shaped by Cathedral Grounds
Mass Ave Heights is bounded by Woodley Road to the north, Massachusetts Avenue to the southwest, 34th Street NW to the east, and Wisconsin Avenue to the west, but almost all of that acreage belongs to the Cathedral, St. Albans School, National Cathedral School, and Beauvoir. The only residential slice is a triangular pocket squeezed between Massachusetts Avenue and Garfield Street, next to the grounds of the Naval Observatory and the Vice President's Residence. Saint Sophia Greek Orthodox Cathedral sits inside the neighborhood's own borders, and Saint Nicholas Orthodox Cathedral is just south of them. The embassies of Cape Verde, Iraq, and Norway are neighbors too.
None of that leaves room for a storefront. So when residents step outside, they're not walking to somewhere commercial. They're walking onto Cathedral land, which provides much of the neighborhood's public walking space.
What's Actually Closed Right Now
The Garth and All Souls Memorial Garden, the interior courtyard tucked against the Cathedral's nave, has been off limits since restoration work began on the central tower. As of this summer, the area sits inside an active construction zone restricted to essential personnel, and the Cathedral has said it doesn't expect to reopen the Garth before late fall 2026, with no firm date yet attached to that estimate.
It isn't the only closure layered onto the grounds this year. Over in Olmsted Woods, the five-acre stretch of oak and beech forest designed as part of the Cathedral's landscape plan, a stone footbridge has been shut since storm damage from a fallen tree, and the volunteer group that maintains the grounds is still weighing whether to repair it or replace it outright. Two separate paths through the same property, closed for two separate reasons, in the same calendar year.
For a neighborhood with no other public square, these closures reduce the available walking routes.
The Walk That's Still Open
Bishop's Garden, on the Cathedral's south side, remains open daily from dawn to dusk, 365 days a year, no ticket required. It's a walled, medieval-style garden with herb plantings, roses, and a Norman arch dating to the 13th century, and from April through October the Cathedral runs docent-led tours for a suggested donation of $10 a guest. If you want a coffee before or after, Open City sits on South Road next to the Cathedral, inside the 1904 Old Baptistry building, serving brunch and lunch alongside the coffee.
All of this belongs to the Cathedral's roughly 57 acres of gardens and grounds, kept up by All Hallows Guild, an all-volunteer organization founded in 1916 specifically to care for and beautify the property. The paths Mass Ave Heights residents rely on every day aren't maintained by the city. They're maintained by volunteers.
Where the Walk Goes From There
With the Garth closed, the loop that's absorbed the traffic runs out through Bishop's Garden and onto Lovers Lane, the walking corridor that threads from the Massachusetts Avenue embassies down through Rock Creek Park and into Georgetown. Anyone who's walked it recently will recognize the sequence:
- South past the embassy buildings lining Massachusetts Avenue, several of them clearly diplomatic residences rather than commercial addresses.
- Onto the paved trail through Rock Creek Park, crossing the creek on a bridge near the Taft Bridge, where the Metro Red Line runs underneath.
- Past Oak Hill Cemetery, visible across the creek.
- Under the Dumbarton Bridge on Q Street, better known locally as Buffalo Bridge for the four buffalo sculptures Alexander Proctor installed there in 1914.
- Along Normanstone Drive and Edgevale Terrace, where the woods sit close on one side and diplomatic residences line the other.
- Into Georgetown, ending at Dumbarton Oaks.
It offers a different destination from the Garth: Dumbarton Oaks, where the gardens have their own hours and entry requirements.
Visiting Dumbarton Oaks Gardens
Dumbarton Oaks is the final stop for anyone finishing the Lovers Lane walk. Its gardens require a timed entry ticket purchased in advance; tickets are not sold at the gate, and 2026 season passes are sold out. The gardens are open March 1 through October 31, Tuesday through Sunday, from 2:00 to 6:00 p.m. The museum side of Dumbarton Oaks has had its own separate closure this year and is scheduled to reopen Thursday, September 3.
Laid side by side, the difference is the whole point:
| Cathedral grounds (Bishop's Garden, Olmsted Woods) | Dumbarton Oaks Gardens | |
|---|---|---|
| Cost | Free | Timed ticket; 2026 season passes sold out |
| Hours | Dawn to dusk, daily | 2:00–6:00 p.m., Tuesday–Sunday |
| Season | Year-round | March 1–October 31 |
| This fall | Open, minus the Garth | Closes for the season October 31 |
The Cathedral grounds are a free, year-round option; Dumbarton Oaks Gardens close for the season after October 31.
What This Means Through the Fall
None of this changes what Mass Ave Heights is. It's still a hilltop pocket of Northwest Washington built around institutional grounds instead of a commercial strip, still walkable in a way that has nothing to do with sidewalk retail. What's changed is the margin. With the Garth shut for tower work and the Olmsted Woods footbridge out, the walking network that residents have always treated as fixed infrastructure has quietly gotten smaller, and the footbridge repair or replacement remains under consideration, while the Cathedral does not expect the Garth to reopen before late fall.
If you already live here, that's worth knowing before you plan a weekend guest's visit around the interior garden, or before you assume Dumbarton Oaks will be waiting once the leaves turn. The workaround exists. It just runs a little longer, and it comes with its own set of closing hours.
For anyone weighing what a neighborhood like this is actually worth, that kind of detail, the ground truth of how people move through a place day to day, tends to matter more than square footage.
