The Bratislava Royal Castle was built in the era of the Roman Empire as a defensive acropolis of the Celts, towering high above the hills of the Danube. Like all other historic castles, it has undergone reconstruction and expansion for various reasons and was changed to the Royal Castle during the Austro-Hungarian Empire. As a carrier of history and culture, the top priority of European city attractions is always the castle. But this is a trip that doesn't have to be a cross, I don't have any burden, and with the dazzling light of many other magnificent castles in Europe, Bratislava Castle really can't be outstanding, so I didn't plan to go up the mountain. Later, in order to go to a Chinese restaurant, I walked from the old town to the foot of the castle. After lunch, I went up the mountain. The scorching sun, and climbed for ten minutes on the mountain road, went to the gate of the castle, I have lost interest in entering, standing on the high point and looking down for a while, and then took a few shots and left.
