The inviolacy of the sacred site was respected by all visitors.
Inviolacy is formed from "in-" (meaning not) and "violare" (meaning to violate or profane) combined with the suffix "-cy" (indicating a state or condition). The word refers to the state of being not violated or profaned, thus representing purity or sanctity.
Think of 'not' ('in-') violating ('violare') something, which helps you remember that inviolacy means the state of being untouched or sacred.
