Does Osaka have historical monuments and buildings?

yes there is. i know theres a castle there because hideyoshi toyotomi built it himself but it was destroyed by the fire for some reason. The castle was rebuilded in somewhat in the 20th century. I know theres a battle in Osaka during the 16th century because when after hideyoshi just died, hideyori whiches hideyoshi's heir was protecting the castle from the enemy led by Leyasu Tokugawa and they might have fire arrows to burn the castle down to ashes I think thats why is the castle set on fire.
