Brno in Three Acts

Start the first morning at Brno's defining hilltop fortress, which spent centuries as one of the Habsburg empire's most feared prisons before reinventing itself as a city museum. Walk the ramparts for an orienting panorama of the city below, then descend through the casemates where the weight of the stone walls alone tells the story.

Down from the castle, Petrov hill holds Brno's great Gothic cathedral, whose twin spires punctuate the skyline from almost every angle in the city. Step inside for the soaring nave, then linger on the terrace outside for another vantage point over the old town rooftops.

A short walk into the old town brings you to the second of Brno's great Gothic churches. St. James is famous for the cheeky stone figure on its tower and, below ground, one of Central Europe's largest ossuary charnel houses — a genuinely arresting underground space only rediscovered in the early 2000s.

Claimed as the venue where the young Mozart performed in 1767, Reduta is one of the oldest Baroque theatres in Central Europe and still hosts opera and drama today. Even if you are not catching a performance, the restored facade and foyer are worth a look — and the connection to Mozart gives the building an unexpected biographical charge.

A ten-minute stroll from Reduta, the Mahen Theatre was the first public building in continental Europe to be lit entirely by Edison's electric light — a fact its neo-Baroque exterior gives no hint of. The auditorium is a marvel of gilded tiers; if no performance is on, linger on the square outside and admire how the building anchors the surrounding streetscape.

Book ahead — tours of this UNESCO-listed Mies van der Rohe masterpiece fill quickly. Built in 1930, the house is a quiet revolution in how space can be organised: the open main floor dissolves the boundary between inside and garden, while the onyx partition wall and travertine columns feel impossibly refined for their era. One of the most important modernist buildings in Europe, full stop.

The only institution of its kind in the world dedicated to Romani history, culture, and art. Permanent exhibitions trace the long journey of Romani people from their South Asian origins across Europe, and temporary shows bring contemporary Romani artists into sharp focus. Thought-provoking and sensitively curated.

The Moravian Gallery spans several buildings; its main Uměleckoprůmyslové muzeum home is a handsome 19th-century palace holding collections of applied arts, graphic design, and fashion that stretch from the Renaissance to the present day. The permanent design and photography collections alone justify an afternoon here.

Founded by the Augustinians in 1350 and closely tied to Gregor Mendel's foundational genetics experiments, St Thomas's Abbey carries more scientific history than most laboratories. The Baroque church interior is richly decorated, and standing in the courtyard it is easy to imagine Mendel patiently counting pea plants in the adjacent garden.

Named after Brno's most celebrated composer, this mid-century opera house is the largest theatre in the Czech Republic. Its 1965 modernist form — clean lines and a sweeping glass facade — contrasts sharply with the ornate 19th-century theatres visited yesterday. Even a slow circuit of the building at dusk, when the interior lighting spills onto the plaza, is a small reward.

The second-largest museum in the Czech Republic occupies the Dietrichstein Palace on Zelný trh square. Collections range from prehistoric Moravian artefacts — including a cast of the famous Venus of Věstonice — through natural history to ethnography. A grounding overview of the land you have been walking through for two days.

Inside the Mendel Square monastery complex, this Baroque basilica shelters a revered 13th-century icon of the Virgin. The gilded side chapels and ceiling frescoes are among the most ornate interiors in the city, and the adjacent monastery garden offers a quiet contrast to the decorated stonework inside.

The Evangelical Church of the Czech Brethren earns its informal name from the warm terracotta brick of its neo-Gothic exterior. Built at the turn of the 20th century, it stands out sharply among its neighbours and the interior — lighter and less ornamental than Brno's Catholic churches — has a calm austerity of its own.

A rocky limestone ridge on the eastern edge of the city, Stránská skála is both a nature reserve and a Palaeolithic archaeological site — human remains found here date back roughly 800,000 years. Walk the marked trails through dry grassland and scrub for wide views toward the Moravian plain, a refreshing outdoor counterweight to a week of interiors.

The tallest building in the Czech Republic outside Prague, AZ Tower's tapered glass form rises above the Brno-střed district as an unmistakable full stop to the city's skyline. Arrive as the afternoon light starts to drop and the city spreads out below in its entirety — castle on one hill, cathedral on the other, and the whole modern fabric stitched between them.
