Pericles is renowned for drastically improving many parts of Greek culture, including architecture but what specific improvements did he make in the field?

All of my own searches mostly turn up articles about the Parthenon, which to my understanding isn't really even considered great in terms architectural innovativeness for the time, its mostly considered great because of the amount of perfection and attention to detail it displays on such a large scale [as well as durability].How exactly did architecture change so drastically with the Golden Age?
