A morning in Dubrovnik is best spent wandering through the older quarters of the city. We would recommend you head for Dubrovnik Cathedral for some early sightseeing (it opens at 9 am), as its beauty is somehow further enhanced when visited on a crisp, peaceful morning. This beautiful Baroque construction is actually not the first church built on the site, and though it's old in its own right, its history is quite remarkable. Originally a Byzantine church, built around the 6th /7th century, it was later followed by a Romanesque replacement in the 1200s purportedly financed by the English King, Richard the Lion Heart who was saved from a shipwreck on the location while returning from one of his crusades. The current version was built in the late-17th century after the old structure was razed down in an Earthquake in the late 1600's. It also happens to house a fascinating treasury filled with old relics, a bonus in addition to its stunning architecture. You needn't be religious to appreciate the beauty and history of the place, nor do you need a particular knowledge of history. It's just a gorgeous attraction that helps you to sink into the general atmosphere of Dubrovnik.
Next, a trip up to the ancient city walls is in order. These walls surround the Old Town and were built hundreds of years ago but are still standing at imposing heights. They can be walked in their entirety, which is a wonderful experience in general. It is particularly enjoyable in light of the television drama Game Of Thrones having been set partially in a CGI-altered Dubrovnik. The thing about Game of Thrones and for that matter any notable fantasy TV series/game, is that fans don't just want to watch - they want to participate. On internet forums you'll find dedicated watchers and readers developing deep theories on the storytelling and which direction the plot will move. As the show forces its viewers to pledge allegiance to a house in westeros, so does a new slot reel game, in its visual theme. It's true, in Dubrovnik, you can come about as close as possible to becoming one of the characters frolicking about in King's Landing.
Following a leisurely walk along the city walls, the best course of action is to find café or coffee shop for a drink and some lunch. Like so many of its European brethren, there's no dearth of cafés serving excellent food. We'd recommend Café Festival, a sidewalk venue in Old Town that allows you to have a bite to eat without feeling like you're retreating from the city. That said, Cave Bar More, built into a cave under a hotel, is an interesting lunch spot too - if a little bit too trendy for its own good!
