Remnants from this earliest period of the building include Romanesque fragments of murals depicting six of the apostles inside the church.

The builders stayed true to Romanesque forms as evidenced by the round-arched portals of the church.

For example, the windows, the vaults of the upper parts of the building, and the blind arch decoration on the west façade are typically pointed.

Tombstone fragments of archaic, trapezoid form have been discovered in the walls of the tower, and it is believed that they may stem from pre-Christian times.

[2] The western facade of the church, decorated with blind arches and the finely sculpted, originally Romanesque portal is especially noteworthy and quite unique in Estonia.

The older parts of the exterior of the church is evidently the product of highly skilled Central European master builders, who probably also worked on constructing Kuressaare Castle, which dates from the same period.

The font is richly decorated with expressive Romanesque sculptures, similar to what can be found e.g. in the northern portal of Riga Cathedral.
