The contest will be judged by an jury consisting of international and Latvian experts, and the winner will be rewarded €150,000.
The expected rebuild will be one of the largest changes the center of Rīga will have seen in the last few centuries, said architect Jānis Dripe, a jury member and expert at the Culture Ministry.

Rail Baltica is a proposed high-speed line to link Helsinki with Berlin through the Baltic capitals by 2024.
The key goal of the project is to renew regional integration by re-joining the Baltic states with the European rail network.
The project will cost Latvia about €1.27b. The first part of the project acquired more than 80% in funding from the Connecting Europe Facility.
Baiba Rubesa, chairwoman of the Baltic joint venture RB Rail, said in late 2015 that the first train to depart after the completion of the project should leave Tallinn for the Lithuanian-Polish border in 2025.
