perdurable
Enduring through ages
Perdurable means lasting indefinitely or enduring through time without change.
The word is formal and literary, carrying more weight than simple "durable"—it suggests permanence that withstands all challenges: the perdurable truths of philosophy, a perdurable monument to human achievement.
