Grand Army Plaza Arch is Restored
June 5, 2025
On June 5, NYC Parks and Prospect Park Alliance held a ribbon-cutting ceremony to celebrate the restoration of the iconic Soldiers’ and Sailors’ Memorial Arch at Grand Army Plaza, Brooklyn’s most significant monumental public artwork. Through $8.9 million in Mayoral funding, the Alliance restored the Arch and the surrounding plaza and landscaped berms.
It is the first significant restoration of this Brooklyn icon in nearly 50 years, and included replacing the roof and reinforcing the historic structure, as well as repointing its beautiful granite stonework to remove years of build-up, staining and spalling; repairing interior elements, including decorative bronze and cast-iron spiral staircases and entrance gates; and designing new, energy-efficient lighting to better showcase the historic elements of the arch and its statuary. In addition, during the Arch’s restoration, the NYC Parks Citywide Monuments Conservation Program cleaned and restored the Arch’s monumental statuary. The project recently received a Lucy G. Moses Preservation Award from the Landmarks Conservancy, its highest honor for excellence in preservation.
NYC Parks Urban Park Rangers will be holding special tours of the Arch on Saturday, June 28. Register for the lottery: prospectpark.org/arch-tour.
“The Grand Army Plaza Arch stands not only as a gateway to Prospect Park, but as a powerful symbol of Brooklyn’s history, resilience, and pride,” said New York City Mayor Eric Adams. “Our administration is dedicated to revitalizing public spaces like the Grand Army Plaza Arch and ensuring that New Yorkers continue to have access to green space throughout the city. This restoration demonstrates our city’s commitment to preserving the landmarks that shape our identity and inspire future generations. Today, we honor the past while building a better, more beautiful future for all New Yorkers.”
“For decades, the Grand Army Plaza Arch has welcomed visitors to Brooklyn’s Backyard while paying tribute to the New Yorkers who gave their lives in the Civil War. Now, thanks to our partnership with the Prospect Park Alliance, this Brooklyn icon has gotten a major facelift, restoring the beautiful statuary and artwork to its original glory,” said NYC Parks Commissioner Iris Rodriguez-Rosa. “By caring for the monuments, statues, and artworks that enhance our public spaces, we’re not just preserving our history – we are communicating to New Yorkers that they deserve the best from their public realm. Parks is proud to maintain over 800 monuments citywide, and we look forward to further partnerships with both the public and private sectors to continue our work as stewards for the city’s outdoor museum.”
“The Soldiers’ and Sailors’ Memorial Arch at Grand Army Plaza is a Brooklyn icon and now once again a shining jewel of the borough. We are so grateful to the Mayor’s Office for providing the funding so that the Alliance could restore the Arch to its original glory, and ensure that it serves as an essential civic space for our community for generations to come,” said Morgan Monaco, Prospect Park Alliance President and Park Administrator. “While triumphal arches typically recognize great military victories and generals, this arch is dedicated to the rank and file, honoring the young men of Brooklyn who lost their lives defending the union in the Civil War. This makes the arch a true monument of the people, welcoming all into Prospect Park and signifying that this is a place where all in our community are celebrated and seen.”
“The Soldiers’ and Sailors’ Memorial Arch has long stood as one of Brooklyn’s most powerful, historical, and iconic symbols,” said Brooklyn Borough President Antonio Reynoso. “This restoration not only brings new life to one of our borough’s most treasured monuments but also revitalizes the heart of Grand Army Plaza for generations of Brooklynites to come. Thanks to Prospect Park Alliance and NYC Parks for their hard work maintaining this historic landmark.”
“I’m thrilled that the restoration of the Grand Army Plaza Arch is now complete, and deeply grateful to the Prospect Park Alliance and the Parks Department for delivering this project on time for the surrounding community and the entire borough of Brooklyn,” said Council Member Shahana Hanif. “This arch is more than a landmark. It’s a gateway to Brooklyn’s Backyard and a powerful tribute to a turning point in American history, reflecting the values we continue to cherish today. I’m especially proud that this restoration was recognized with the Lucy G. Moses Preservation Award, the highest honor for preservation efforts from the New York Landmarks Conservancy. Brooklyn deserves nothing less.”
“The Soldiers’ and Sailors’ Memorial Arch is an iconic portal to one of the city’s most beautiful parks — one that deserves to stand in its full glory. For many, this historic arch represents the heart and soul of Brooklyn past, present, and future,” said Council Member Crystal Hudson. “Thanks to the Prospect Park Alliance and NYC Parks, New Yorkers will visit the park and admire this landmark for generations to come.”
“The Arch is more than just the gateway to Grand Army Plaza and Prospect Park—it’s an iconic symbol of Brooklyn’s greatness and of what we can accomplish when we work together,” said State Senator Andrew Gounardes. “Public works like the Arch are a part of our history and our collective heritage, and New Yorkers deserve beautiful, well-maintained public spaces that both honor that history and meet our needs today. This restoration does exactly that, and ensures the Arch will stand proudly as we walk together into the future. Thanks to the Parks Department, the Prospect Park Alliance for this crucial, powerful work.”

As a proud Brooklynite, I’m grateful to see this monument restored with such care and vision. I commend the Prospect Park Alliance, NYC Parks, and all partners involved for their dedication to preserving the legacy of Grand Army Plaza,” said Assemblymember Brian Cunningham.
“The Soldiers’ and Sailors’ Memorial Arch is one of the most powerful symbols of Brooklyn’s commitment to freedom and racial equality,” said Assemblymember Phara Souffrant Forrest. “I’m thankful to the NYC Parks Department and Prospect Park Alliance for their dedication in overseeing the restoration of this incredible monument and maintaining Grand Army Plaza as a vital community hub.”
Background on the Arch and Grand Army Plaza Restoration
Famed Prospect Park architects Frederick Law Olmsted and Calvert Vaux designed Grand Army Plaza as the grand entrance to Prospect Park at the time of the park’s creation in 1867. In 1892, the plaza became the site of the Soldiers’ and Sailors’ Memorial Arch, dedicated to those who sacrificed their lives defending the Union during the Civil War.
The arch was designed by American architect John H. Duncan, who also designed Grant’s Tomb. At the time it was considered Brooklyn’s Arc de Triomphe, one of the most famous monuments in Paris. The arch is adorned with three bronze statuary ensembles by the Brooklyn-born Beaux Arts sculptor Frederick William MacMonnies, who was also a highly accomplished painter and portraitist. The arch also includes statuary by artists Philip Martiny and William Rudolf O’Donovan, as well as equestrian bas-reliefs by famed American artist Thomas Eakins. It is one of New York City’s three major triumphal arches.
The arch was landmarked in 1975, when the structure was in such severe disrepair that the statue on top of the arch, the quadriga of Columbia, literally fell from her chariot. In 1976, the City undertook a comprehensive restoration. The fall of the quadriga became the symbol of the greater need for support for Prospect Park, which led to the founding of the group that would become Prospect Park Alliance.
To restore the Arch, the Alliance’s in-house team of award-winning architects conducted significant research to uncover the historic design. Original blueprints were lost to time, requiring the Alliance to create a detailed scan of the inner structure using radar and magnetic investigation. Through these scans, and physical surveys and drawings from previous restorations, the Alliance embarked on a comprehensive restoration. This included reinforcing the historic structure with new steel beams and creating a new internal drainage system. After laboratory testing, the team determined the composition of the stonework mortar, Rosendale cement from the namesake town in upstate New York, and utilized this in the restoration. In addition, cracked and broken stonework was replaced to match the existing stone from a quarry near the original source in Maine. On the interior, bronze and cast-iron spiral staircases and entrance gates were carefully disassembled for restoration: original elements were meticulously cleaned, missing elements recreated, and then the renewed piece was reassembled on site.
The Alliance also restored the landscaped berms that frame the plaza on its east, west and north sides. This work included removing invasive plants, trees and shrubs; and planting 194 native trees, as well as new plants and shrubs that provide interest and color throughout the seasons. The Alliance also replaced a chain link fence with low, decorative steel fencing. At the plaza, the Alliance restored the broken bluestone and granite paving around Bailey Fountain and the John F. Kennedy Memorial and added a new ADA-accessible curb cut at the north entrance to the plaza.
