Brno Day Trip from Prague — Catacombs, Castles and the Czech Second City

Brno is the city Praguers either love or pretend doesn't exist. The Czech Republic's second city, capital of Moravia, home to 400,000 people and two major universities, Brno has spent decades in Prague's shadow and seems perfectly comfortable there. It has none of Prague's tourist crowds and all of its own architectural depth — Romanesque crypts, a Gothic castle on a hilltop, a Functionalist masterpiece in Tugendhat Villa, and a network of catacombs beneath the old town.

Two and a half hours from Prague by train, Brno fills a day with enough variety to justify the journey. The city rewards curiosity more than checklists.

What to See

Špilberk Castle

Hrad Špilberk dominates Brno from a hilltop at the city's western edge. Originally a 13th-century royal castle, it was converted into one of the Habsburg Empire's most feared prisons in the 18th century. Prisoners from across the empire — including Italian revolutionaries and political dissidents — were held in the underground casemates, and the fortress earned the reputation as "the prison of nations."

Today, the casemates are open to visitors — narrow passages, barrel-vaulted cells and atmospheric lighting that gives a genuine sense of the conditions. The castle also houses the Brno City Museum, covering the city's history from prehistory to the present. The castle park surrounding the fortress is Brno's main green space — popular for jogging, picnics and evening strolls.

Insider detail: The walk up to Špilberk from the city centre passes through the park and takes about 15 minutes. From the ramparts, the view over Brno's red rooftops is the city's best panorama. The spires of the Cathedral of SS Peter and Paul are directly east, and on clear days you can see the Moravian hills to the south.

Tugendhat Villa

Vila Tugendhat is the most important piece of modern architecture in the Czech Republic. Designed by Ludwig Mies van der Rohe and completed in 1930, it was built for the Jewish industrialist Tugendhat family and is now a UNESCO World Heritage Site. The house pioneered the open floor plan, floor-to-ceiling glass walls and a floating chrome-and-onyx partition that became icons of Modernist design.

Tours run on a strict timed-ticket system. Book well in advance — summer slots sell out weeks ahead. The exterior is visible from the street (the garden side faces down the hill), but the interior tour reveals why this building changed architecture.

Insider detail: The famous onyx wall in the living area — a single slab of honey-coloured stone from Morocco — changes colour depending on the light. Morning tours see it glow warm amber. Afternoon light through the garden windows turns it cooler. The guides know this and time their explanations accordingly.
