PORTSMOUTH, N.H. — Churches, museums and schools are taking part in a bell-ringing in New Hampshire to mark the 107th anniversary of the Treaty of Portsmouth, which ended the Russo-Japanese War.

In 1905, President Theodore Roosevelt invited envoys of Russia and Japan to the United States to negotiate an end to the war. The peace conference was held at the Portsmouth Naval Shipyard in nearby Kittery, Maine, that summer. The Treaty of Portsmouth was signed at 3:47 p.m. on Sept. 5. Roosevelt won the 1906 Nobel Peace Prize for his efforts.

The anniversary is being noted at 3:47 p.m. Wednesday by the simultaneous bell-ringing in Portsmouth. A talk is scheduled for 6 p.m. at the Discover Portsmouth Center to celebrate the 100th anniversary of Portsmouth’s cherry trees — a gift from Japan.
