Replicas of Columbus' Nina and Pinta arrive today and will be open to the public beginning tomorrow through Wednesday in Norwich. The Nina is a hand built, exact size replica owned by the Columbus Foundation educational group. The Pinta was also built with no power tools and is slightly larger than Columbus' original ship. The ships will be docked at the Marina at American Wharf. The admission price is $8 for adults, $7 for seniors and $6 for students. Children 4 and under are free.
