The historic core comprises the area of Vnitřní Město part of Trutnov, with Krakonoš Square (Krakonošovo náměstí) in its centre. The area was delimited by town walls in the 14th century. Their fragments are preserved to this day. The landmark of the square is the neo-Gothic Old Town Hall, nowadays the tourist information centre. In the middle of the square are a statue of Joseph II, a stone fountain with statue of Krakonoš, and the baroque Holy Trinity Column from 1704.
