Vandals struck the Lili‘uokalani Gardens teahouse in Hilo late Thursday or early Friday.

A large graffiti tag sprayed across one wall of the teahouse was discovered Friday morning, the Hawaii Tribune-Herald reported. A similar tag was found on the park’s bathroom.

“I won’t call it graffiti or tags or street art,” said K.T. Cannon-Eger, president of the Friends of Lili‘uokalani Gardens. “This is vandalism.”

Although the graffiti on the bathrooms was quickly painted over, the vandalism to the teahouse will be more difficult to remove.

Roxcie Waltjen, director of the Hawaii County Department of Parks and Recreation, said much of the wood used in the teahouse’s construction was imported from Japan and requires a special cleaning solution and soft scouring pads.

The building, called Shoroan, is the second teahouse built in the park. The original building, built in 1972, was a gift from the Urasenke School of Tea in Japan for the Urasenke Hilo Association to practice traditional Japanese tea ceremonies.

The original teahouse was destroyed by arson in 1994. It was rebuilt and opened in 1997 at a new location in the gardens.
