2 Best Sights in Gornji grad (Upper Town), Zagreb and Environs

Nestled among the regal buildings of the Croatian parliament, the original church building was erected in the 13th century and was once the parish church of Gradec. The Baroque bell tower was added in the 17th century, and the steeply pitched roof—decorated in brilliant multicolor tiles arranged to depict the coats of arms of Zagreb on the right and the Kingdom of Croatia, Dalmatia, and Slavonia on the left—was added during reconstruction in the 19th century. It underwent another reconstruction in the first half of the 20th century. At that time, renowned painter Jozo Kljaković painted its walls, while the altar was decorated with works of famous sculptor Ivan Meštrović.  At the time of this writing, the church's interior was closed for renovation, but the exterior is well worth a look. 

Dedicated to the Assumption of Mary and to the kings St. Stephen and St. Ladislaus, this cathedral was built on the site of a former 12th-century cathedral destroyed by the Tatars in 1242. The present structure was constructed between the 13th and 16th centuries. The striking neo-Gothic facade was added by architect Hermann Bollé following the earthquake of 1880, its twin steeples being the identifying feature of the city's skyline. Behind the impressive main altar are crypts of Zagreb's archbishops and Croatian national heroes. The interior is imposing and inspires silent reflection. Don't neglect the north wall, which bears an inscription of the Ten Commandments in 12th-century Glagolitic script. The cathedral's face is ever-changing, as its towers are being reconstructed again following the earthquake that hit Zagreb in 2020.  At the time of this writing, the interior is closed for renovations.
