Vyšehrad
On our third day we visited Vyšehrad, which means "upper castle" in Czech. It is the site of the first Czech King's residence where the Premysl Castle was situated in the 10th Century. We spent some time exploring the Vyšehrad Cemetery and the Church of Saints Peter & Paul (ABC = Another Big Church).
Later, I found a cool boutique with locally-designed clothing and jewelry, a cute coffee shop (Onesip Coffee), and a little restaurant with the most delicious Vietnamese food (Bánh Mì Makers).
