Lučenec is a small town and the attractions are modest, but it rewards a few hours of unhurried exploration. The old town centre has a mix of Art Nouveau and neo-Gothic architecture from the late 19th and early 20th centuries, when the town was part of the Kingdom of Hungary and prospering from trade and agriculture.
The Lučenec Synagogue is the most architecturally significant building in the town — a large Moorish-revival structure that once served one of the largest Jewish communities in the region. The surrounding volcanic hills of the Novohrad region make for pleasant walking and cycling.
