In Winter 2024, Please Touch Museum began a $4.2 million project to renovate the marble flooring in Memorial Hall in advance of the building’s 150th anniversary celebration in 2026.
About Memorial Hall
Memorial Hall was built as the art gallery for the 1876 Centennial Exposition, the first World’s Fair to be held in the United States.
Construction on Memorial Hall began in 1874 and was completed in 1876. Over 200 buildings were constructed for the Centennial Exposition; Memorial Hall is one of just two Centennial buildings still standing, and was added to the National Register of Historic Places in 1976.
Over the past 150 years, the building has served as a museum, office space, a police station, and a community center. Memorial Hall has been home to Please Touch Museum since 2008.
About the Floor
Memorial Hall is an early example of monumental Beaux-Arts architecture. The floors are original to the building, and are comprised of white, red, and black marble.
Ulysses S. Grant, Frederick Douglass, Thomas Edison, and John Wanamaker are just a few of the famous figures who might have trod Memorial Hall’s marble floors during the Centennial Exhibition in 1876.
Underneath the marble is the building’s original mortar substrate, which has deteriorated over the decades and lost its adhesive powers, leading to wobbly and broken tiles.
Over the past 150 years, wear and tear has necessitated the replacement of many of the original marble tiles. Some replacement tiles are not close matches to the original tile grain. Many of the remaining original tiles are cracked, chipped, or otherwise damaged.
The Renovation Process
Please Touch Museum began the floor renovation project in Winter 2024, working in stages to preserve the floor’s original design.
Project managed by Aegis Property Group and conducted by Knapp Masonry, the renovation process took place one 200-square-foot section at a time. The marble was removed one tile at a time, and replaced with tiles that are close matches to the original in both appearance and origin, coming from quarries nearby the originals in France, Spain, and Italy.
The Museum remained open to visitors for the duration of the project, allowing families to view the construction and renovation work up close. The construction materials were removed from the floor completely during all private event rentals, so that weddings, proms, special occasions, and corporate events were not impacted.
Funding the Floor Project
Please Touch Museum raised additional funds to complete this important work.
The funding needed to complete this project has been raised thanks to generous support from Pennsylvania’s Redevelopment Assistance Capital Program, the City of Philadelphia, the U.S. Department of the Interior’s Save America’s Treasures program, the Hamilton Family Charitable Trust, the McLean Contributionship, and Please Touch Museum trustees and other individual donors.
Please Touch Museum closed the funding gap through the support of individual donors committed to preserving this historic building.
Memorial Hall 2026 was a campaign to restore Memorial Hall to its original glory in advance of its 150th anniversary in 2026, and included the floor restoration and work on the intricate exterior facade.

What is the history of Memorial Hall?
Memorial Hall was built as the art gallery for the 1876 Centennial Exposition, the first World’s Fair to be held in the United States. Construction began in 1874 and was completed in 1876. Over 200 buildings were constructed for the Centennial Exposition; Memorial Hall is one of just two Centennial buildings still standing, and was added to the National Register of Historic Places in 1976.
Since the Exposition, Memorial Hall has been home to several organizations. From 1877 to 1928, the Pennsylvania Museum and School of Industrial Art used Memorial Hall as its museum. Since 1958, Memorial Hall has served as the Fairmount Park Commission offices, a police station, and community center.
By 2000, the building had fallen into disrepair and was mainly used for storage. The Fairmount Park Commission sought a new tenant to help restore the building to its former grandeur. The Please Touch Museum signed an 80-year lease for the building in 2005 and began extensive renovations.

What was the process and how long did it take?
The entire process took 15 months. The work was done in stages, 200 square feet at a time.
Work that will produce air particulates will take place under tents fitted with a HEPA filtration system and will occur in the early morning hours, well before visitors arrive, and air filtration systems will vent outside.
The remaining work took place surrounded by clear panels so children and families could watch this construction and renovation work in process as an educational opportunity.
In each section of the floor:
• The marble tiles were removed.• What remains of the original substrate was ground up. This substrate has lost its adhesion over the decades, which has led to more breakage of tile. The material is organic and its disposal complies with EPA guidelines.
• A new substrate was poured and allowed to cure for 24 hours.
• New mortar was added, marble tiles were set in place in accordance with the original design, grouted, and allowed to set.

Where was the new marble sourced?
The replacement marble came from quarries in Italy, where it is believed the original marble was also procured, along with quarries in France and Spain.
-
What happened to the marble that was removed?
Some original marble remains at Memorial Hall, used in Meeting Room West as part of an 1876 reflection space. This initiative is in the early stage of planning for design and funding. We sourced a reseller who sold it for other historic preservation projects. Marble that was obviously used for repairs over the years and is not original to the building, along with original marble in poor condition, was disposed of in landfills designed to hold stone.

Was it safe to be in the Museum while this work was being done?
Yes. The flooring materials were tested and are safe.
Work that produced air particulates took place under tents fitted with a HEPA filtration system and occurred in the early morning hours, well before visitors arrived, and air filtration systems vented outside.
