You're drawing the wrong conclusions. Blueblood is a mortal unicorn and the castle would have been abandoned 1,000 years before he was born. Cadence (depending on which origin story you accept) either ascended to be an alicorn after Nightmare Moon's exile or is about Shining Armour's age (younger even than Blueblood!).

In any case, Cadence's castle is and always has been the Crystal Palace as she is the Princess of the Crystal Ponies.
