A temporary shrine was erected on the site of the attack while plans and fundraising for a more permanent memorial were undertaken. In order to build a permanent shrine on the exact spot where the assassination took place, it was decided to narrow the canal so that the section of road on which the tsar had been driving could be included within the walls of the church. An elaborate shrine, in the form of a ciborium, was constructed at the end of the church opposite the altar, on the exact place of Alexander's assassination. It is embellished with topaz, lazurite and other semi-precious stones, making a striking contrast with the simple cobblestones of the old road, which are exposed in the floor of the shrine.[3]
