Located in the former Moscow Suburb (now Latgale district) is the Church of the Annunciation of Our Most Holy Lady. It's often called the Church of St Nicolas the Miracle Worker.

In the early 18th century there were already 2 Russian wooden churches in existence by the Charles Gate, but these disappeared in 1773, due to extension of Riga's fortifications. The church, which dates from 1774-1778, stands on a plot by the so-called "Guest Yard".

During the war between Russia and France in 1812, all Riga's suburbs burned down, as well as this church. A design for a new church, in Classical style, appeared in 1813. The new church was built between 1814 and 1818. In 1827 the church received a donation in the form of a 6,150 kilograms bell cast. Extensive repairs occurred in the 19th century, adding a glass porch.
