RINGWOOD - The historic Ringwood Manor is now open again.

Two years ago, a furnace malfunction covered the site in an oily soot, and the manor had to undergo a $1.6 million restoration.

The restoration uncovered some surprises, including a letter from a French artist found behind a painting that dates back to 1780.

The estate once housed the American Iron Company, which provided material for American troops during the Revolutionary War.
