In special cooperation with the parish of Martin's Evangelic Lutheran Church, architect Peters Blums and the National Cultural Heritage Administration of Latvia, for two years AM studio stained glass masters have been restoring and are still continuing the restoration work of stained glass windows in Martin's Evangelical Lutheran Church in Riga.

Hundreds of pieces of glass, by hand, have been carefully cleaned, remade, painted, soldered and encased with the utmost respect, leaving as much of the authentic glass as possible and respecting the principles of restoration.
