DELAWARE TOWNSHIP - (AP) - Officials say the fire that damaged a historic New Jersey inn that once hosted George Washington is not suspicious.

Investigators say Monday's blaze at The Sergeantsville Inn in Delaware Township appears to have started in a waiter's station adjacent to the bar. But they do not know what sparked the blaze.

Flames heavily damaged the two-story stone structure that is more than 300 years old.

According to its website, The Sergeantsville Inn was converted from a private home into a grain and feed store in the 1830s. The restaurant opened in the early 1900s.
