Battle site and museum

Hi,

I am a history researcher and I have two questions.

1. I heard that there is a museum that is dedicated to the "Battle of Lushun" (Lushunkou Port or Port Arthur) which was fought in 1894 during the 1st Sino-Japanese War (1894-95) and again during the Russo-Japanese War (1904-1905) during the "Siege of Port Arthur" (Lushunkou Port) which was fought from August 1904 to January 1905. Can you tell me the museum's location, hours, how to get there, etc.?

2. Is the battle site preserved? If so, where is it, how to get there, etc.?

Thank you for your time and assistance.
