"Have fun storming the castle!" You won't be able to help yourself repeating that famous line from the Princess Bride while visiting Carrickfergus Castle. This castle, originally built in 1066... let me say that again, 1066!!!!, is still in remarkable condition! For only 5 and change, you gain entrance to this amazing piece of history and can even have a FREE guided tour (which I would almost insistently recommend). Easily the best venti latte worth I've ever spent. Our guide traced the history through 1066 up until the 1920s (I think - ask on the tour) when it was finally turned over for preservation. All that time, the castle has served in some capacity or another, which is why it's been so well maintained. You literally can walked through over 1000 years of history in one building and SEE it all pretty much as it was (and in many places, still is.)
I learned so much from my visit there about the castle and history in the region... it truly exceeded every single expectation 10 fold. My favorite tidbits where the innovative "indoor plumbing" and the bit about how to invade the castle (but you don't have to worry about that... just give them a few quid and they let you walk on in.) You can explore on you own but I honestly think you'd be missing out on just how amazing this structure is historically, architecturally, and archeologically if you passed up the guided tour. IT'S FREE with the price of admission. You will also be able to capture some stunning photos of Carrickfergus and it's outlying countryside from the castle walls.
Extra tip - If the tide is out, make a trip down onto the beach and walk the outside of the castle along the sea. Gives you another perspective of just how imposing the castle is/was plus you may find some unexpected visual treasures, especially if you're into photography.
