Riga Cathedral () is the Protestantcathedral in Riga, Latvia. Built near the River Daugava in 1211 by Albert of Riga, it is considered the largest medieval church in the Baltic states. It has undergone many modifications in the course of its history. David Caspari was rector of the cathedral school in the late 17<sup>th</sup> century. His son Georg Caspari also served at the cathedral.
It is often known in English as the Riga Dom Cathedral (although it has no dome, the nickname comes from the Latvian Doms and German Dom meaning "cathedral")
Certainly one of the most recognisable landmarks in Latvia, the Cathedral is featured in or the subject of paintings, photographs and television travelogues.
