The renowned cylinder mill of Matsopoulos (previously known as Agathoklis’ mill) was constructed in 1884; it ground tons of cereals from the whole of Thessaly plain and it is an important example of industrial architecture. It is a four-storey building with stone walls decorated with bricks laid in ‘bands’, with exceptional interior mechanical and wooden machinery. The Mill is closely associated with the course of growth the city enjoyed after its liberation from the Ottoman rule. The industrial complex of Matsopoulos Mill was donated to the municipality of Trikkaioi in 1977 and at present, after its restoration, serves as an industrial monument and municipal cultural centre with cultural event facilities (congress centre, theatre, cinema). Matsopoulos Park, covering an area of one hundred square kilometers, is important as a green zone providing fresh air and contributing to the aesthetics of the city.
