Back in the Summer of 2018 when we had the massive heatwave I had a weeks holiday to Paris, while there we had a day trip to the Palace of Versailles to see the stunning architecture and the sprawling grounds.
Being June time there were massive queues to get in meaning we had to stand in the scorching sun waiting to get in, so if you are planning on going I would recommend booking tickets in advance.
The palace is now classed as a UNESCO World Heritage site having being the royal residence for Louis XIV until the start of the French Revolution.
