Tempietto, or a "little temple" designed by the architect donato bramante, was erected in rome, italy, during the high renaissance era, and was built above the place where it is believed that saint peter was:

The Tempietto del Bramante dates back to 1502, and it was erected as a “martyrium” to remember the execution of St. Peter. Below the round room there is a crypt, where a plaque on the floor protects the hole that was supposedly left from the cross of St. Peter.

The building was ordered by the Spanish royal family because of a vow made for the birth of their first son, John, who dies in 1497.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
