More than a month ago, I bought 2 tickets directly online (10 Euros each) to visit the Royal Place in Madrid on Monday April 16 at 5 pm. I just received an e-mail advising that the tickets were cancelled, and that I would receive a refund, because "for official causes" the Palace will be closed. This is disappointing as we were looking forward to this visit during our short trip to Madrid, April 16 -April 18. This was one of the main sites we wanted to see in Madrid, and we even booked our Hotel near the Palace for that reason.
I went back online and booked Tuesday April 17 at 4:30 pm, and downloaded the tickets, although another page on the site seems to say that they are also closed on that date. Then I received another email cancelling those tickets for the same reason.
What is happening on April 13 through April 21 to cause this closing.? I understand that it is for some official event(s) but I wonder what; as it it will be for several days and we will be nearby?
