The Wallace Monument is a picturesque Gothic structure and is in a prominent situation, built to commemorate William Wallace at the time of an upsurge in the Scottish desire for self-determination, predating the 1869 Wallace Monument at Stirling.
Robert Snodgrass built a square plan Gothic tower in 1855–1857 from polished sandstone ashlar blocks, 3-stage, 3.7 m wide at the base, 18 m high, with a pinnacled parapet. Base course; string courses; corbelled, shouldered band course between 2nd and 3rd stages; machicolated, crenellated parapet with thistle-finialled, conical-capped circular angle pinnacles and ball-finialled, ogee-capped square-plan wallhead pinnacles. Diagonally-boarded timber door in Tudor-arched, roll-moulded doorway with hoodmould to the south-east elevation; similar inscription recesses at other elevations. Round-arched recesses at 2nd stage; paired round-arched recesses at 3rd stage.
The Wallace family coat of arms and their motto 'Pro Libertate Patriae' are located above the entrance, carved by John Logan, a local sculptor.
A spiral staircase leads up to the viewing platform and the arms of the Wallace family are blazoned in bas-relief above the entrance door.References:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
