I visited a Gilded Age mansion once called 'the American Versailles.' These 7 details left me speechless.

• Lynnewood Hall, a 110-room estate in Pennsylvania, was completed in 1899.
• Two of its heirs perished in the sinking of the Titanic, and it later lay vacant for 30 years.
• As restoration efforts get underway, it’s open to the public for the first time in eight decades.

A bathroom that’s a century old looked surprisingly modern.

The marble sink and high interior archway hovering over the bathtub gave a contemporary feel.

Although the mansion was completed in 1899, parts of it, including the ballroom, were remodeled in the early 20th century.

Gilded-Age design was all about the details.

I was struck by the attention to detail on every inch of the property, including design efforts put into the smallest things, like a light switch fixture adorned with a religious inscription.

The mansion’s architecture boasts large, high-paneled windows that flood even the tiniest rooms (like this butler’s pantry) with lots of light. It makes the indoor experience feel as bright as the outside.

Even the ceilings were ornate.

Just when I thought I couldn’t be more amazed by everything I saw in front of me, I looked up.

In modern design, I rarely see architects take the time to decorate the ceiling … except for that atrocious ’90s popcorn-ceiling trend.

The wood-and-gold square-paneled ceiling of the grand ballroom was a nice touch.

More than 125 years after its grand opening — and the triumphs and tragedies that followed — Lynnewood Hall is beginning a new chapter.

Visitors can see “The Gilded Age”-inspired Fleur de Villes floral exhibit through October 4 at the property in Elkins Park, Pennsylvania.

For now, it’ll be the public’s only chance to walk the halls of the historic home. As restoration continues, the Lynnewood Hall Preservation Foundation plans to host scheduled tours, further special events, open houses, and volunteer days, although dates for these have not yet been announced.
