So on a gorgeous day in March 2017 we decided to go again. As you approach the sheer scale of the placed is striking – the gold roofs sparkling over the vast coach park in front of the building. You walk past the array of multinational coaches to a huge courtyard filled with people queuing. Following the signs you find a queue for the tickets and then join it. Most people ignore the automated ticket machines – so we bought our tickets – 18 euro each and re-joined the main queue. Eventually we got to the security scanners where they were obsessed with selfie sticks and took mine away.
