The undisputed centrepiece of Našice is Pejačević Castle (Dvorac Pejačević), a Baroque-Classicist building completed in 1811-1812 by Count Vincencije Ljudevit Pejačević, who had inherited the Našice estate from his father, Karlo III Ferdinand. Set atop a low rise within a vast English-style landscape park, the castle was significantly enlarged in 1865, when the rounded corner towers that give it its present silhouette were added, and the building took on most of its current appearance around 1850 under Count Ladislav Pejačević. The castle today houses the Town Museum (Zavičajni muzej Našice), with a recently renovated permanent exhibition that traces the history of the town and the noble family who shaped it. Walking through the castle’s halls and the surrounding grounds, visitors follow in the footsteps of the family’s most famous member, the composer Dora Pejačević (1885-1923), widely regarded as the first modern Croatian composer, whose intricate piano, violin, and cello sonatas, written partly during her years in Našice, remain among the treasured works of Croatian musical heritage.

A short walk through the park leads to the Small Pejačević Manor, a more modest Neoclassical Revival building, sometimes called the hunting house, built in the early twentieth century with geometric box-hedge gardens of its own. The manor is a quietly remarkable piece of engineering for its time, built on a reinforced concrete trough specifically designed to protect the structure from the high groundwater typical of the surrounding Slavonian plain, an early and pioneering solution for a problem that affects many buildings in this low-lying region. Today the building serves as a school, though its gardens remain part of the wider visitor circuit through the park.

In the centre of town stands St. Anthony’s Franciscan Church (Franjevačka crkva sv. Ante Padovanskog), an eighteenth-century Baroque church whose vivid yellow tower has become one of the most recognisable landmarks of Našice. The church stands on ground with a much older religious history: the Knights Templar first established a presence here in the thirteenth century, before the site passed to the Franciscans, who built the present church and an adjoining monastery whose library still holds a small number of historic early printed books. The church remains an active parish today, its bright tower visible from much of the town centre, and a beloved statue of St. Anthony stands in the nearby town square, a popular gathering point for evening strolls and the local café culture that gives Našice’s centre its quiet, sociable atmosphere even on a misty winter evening.

The largest single attraction in Našice, however, may simply be the Pejačević Park (Park Pejačević) itself, one of Croatia’s most celebrated landscape parks and the green setting that ties the castle, the manor, and the town together. Laid out originally as part of the Pejačević family’s nineteenth-century estate, the park combines a tranquil ornamental pond, centuries-old oak trees, winding shaded paths, and a cascading garden that changes character completely with the seasons, from the lush green of summer to the golden colours of autumn and the frost-covered stillness of winter. For travellers with a little more time, the park alone is worth an unhurried hour, whether for a quiet walk, a rest beside the pond, or simply to take in one of the better-preserved aristocratic landscapes of eastern Croatia.

The Našice Grad station sits closest to the centre, with Pejačević Castle, the Franciscan church, and the surrounding park all reachable on foot in around ten to fifteen minutes along flat, well-signposted streets. Travellers arriving at the main Našice station, a short distance further out, can cover the remaining stretch into town in about fifteen to twenty minutes on foot or a few minutes by bike. The historic core itself is compact and easy to navigate, with the castle and its park forming a single connected green space at the heart of the town. Bike racks are available near the main town square. For onward travel, the same rail connections run back toward Osijek and the wider Danube region, so Našice works equally well as a half-day excursion or as a longer stop combined with neighbouring Slavonian towns.
