Battle of San Pietro Infine: The Battle of San Pietro Infine (commonly referred to as the "Battle of San Pietro") was a major engagement from 8–17 December 1943, in the Italian Campaign of World War II involving Allied forces attacking from the south against heavily fortified positions of the German "Winter Line" in and around the town of San Pietro Infine, just south of Monte Cassino about halfway between Naples and Rome.  The eventual Allied victory in the battle was crucial in the ultimate drive to the north to liberate Rome.  The battle is also remembered as the first in which the troops of the Royal Italian Army ("Regio Esercito") fought as co-belligerents of the Allies following the armistice with Italy.  The original town of San Pietro Infine was destroyed in the battle; the modern, rebuilt town of the same name is located a few hundred meters away .

San Pietro Island: San Pietro Island (Italian: "Isola di San Pietro", Ligurian Tabarchino: "Uiza de San Pé", Sardinian: "Isula 'e Sàntu Pèdru") is an island approximately 7 km off the South western Coast of Sardinia, Italy, facing the Sulcis peninsula.  With 51 km2 it is the sixth largest island of Italy by area.  The approximately 6,000 inhabitants are mostly concentrated in the fishing town of Carloforte, the only "comune" in the island.

San Pietro di Castello (church): The Basilica di San Pietro di Castello (English: Basilica of St Peter of Castello ), commonly called San Pietro di Castello, is a Roman Catholic minor basilica of the Patriarch of Venice located in the Castello "sestiere" of the Italian city of Venice.  The present building dates from the 16th century, but a church has stood on the site since at least the 7th century.  From 1451 to 1807, it was the city's cathedral church, though hardly playing the usual dominant role of a cathedral, as it was overshadowed by the "state church" of San Marco, and inconveniently located.  During its history the church has undergone a number of alterations and additions by some of Venice's most prominent architects.  Andrea Palladio received his first commission in the city of Venice from the Patriarch Vincenzo Diedo to re-build the facade and interior of St Pietro, but Diedo's death delayed the project.

Pond hockey: Pond hockey is a form of ice hockey similar in its object and appearance to traditional ice hockey, but simplified and designed to be played on part of a natural frozen body of water.  The rink is 50 to 80 percent the size of a standard NHL-specification rink, and has no boards or glass surrounding it; usually only a barrier of snow keeps the puck in play.  In addition, because there are no protective barriers behind the goal to contain high errant shots, the top of the goal is lower, in fact only slightly taller than the width of a puck, and the game does not have a formal goalie.  Because of these differences, pond hockey places more emphasis on skating and puckhandling ability and less on shooting and checking.  Non-competitive pond hockey is played with improvised goals, rinks of a variety of sizes, and no boards or snow barriers.
