The historical town of Tornio was a significant hub of trade and transport. Tornio was the gateway to the north. The observatory of Anders Hellant<\/em> in Tornio was famous among academics in the 18th century. The Frenchman Maupertuis<\/em> conducted his measurements of 1736\u201337 using the Tornio church tower. J\u00f6ns Svanberg<\/em>, who was born in Alakainuu and went to school in Tornio, also took measurements in Tornio right at the start of the 19th century, when the high tower of the Alatornio church had already been built (finished in 1797). After this, Alatornio church was used as a station point for the triangulation of the Struve Geodetic Arc. It is one of the few buildings used as a station point for the triangulation chain spanning 2,800 kilometres.<\/p>\n <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ use_custom_gutter=”on” make_equal=”on” admin_label=”alatornio-church” _builder_version=”4.8.2″ _module_preset=”default” background_color=”RGBA(0,0,0,0)” width=”100%” module_alignment=”center” custom_margin=”8px|8px|8px|0px|false|false” custom_padding=”8px|8px|8px|8px|false|false” border_color_all=”#E28103″][et_pb_column type=”3_5″ _builder_version=”4.8.2″ _module_preset=”default” background_enable_color=”off”][et_pb_image src=”https:\/\/blogi.eoppimispalvelut.fi\/struvenorth\/files\/2021\/08\/DSC_2524-2-Kirkko.jpg” title_text=”Alatornio church” show_bottom_space=”off” align=”center” _builder_version=”4.8.2″ _module_preset=”default” width=”98%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false”][\/et_pb_image][et_pb_text _builder_version=”4.8.2″ _module_preset=”default” text_font=”Raleway|600|||||||” background_color=”#d1e5ec” width=”95%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false” custom_margin__hover_enabled=”on|desktop”]<\/p>\n The Alatornio church is located on the Pirkki\u00f6 island, where measurements were taken by scientist from Russia and Sweden.

The elevations of the measuring points near the church were measured in the autumn of 1842, and the triangulations in the south were finished by 1844. The measurements were taken under the supervision of the Finnish Fredrik Woldstedt<\/em>, who worked for the Pulkovo Astronomical Observatory of the Russian Academy of Sciences in Saint Petersburg. Woldstedt worked closely with Struve.<\/p>\n The Swedes measured the angles between the southernmost stations of the Lapland portion of the chain in 1849. The southernmost triangle was formed by the Alatornio church, Kaakamavaara and Per\u00e4vaara station points. The leader of the Swedish expedition was Nils Haqvin Selander<\/em>, an astronomist and a member of the Riksdag of the Estates This means research groups from both nations worked in the area.<\/p>\n The Alatornio church and the Kokkom\u00e4ki hill nearby were both used as station points for the triangulation. The Russian Academy of Sciences was in charge of the Kokkom\u00e4ki station point and the Royal Swedish Academy of Sciences was in charge of the station point at the church. The church is visible from a large distance, and the view from the church tower also reaches far. The measurements were taken on the bell chamber balcony, which is slightly to the side from the centre of the tower. The centre of the tower also had to be determined by using triangulation.<\/p>\n The measuring instrument was most likely placed on a separate table on the bell chamber balcony. The table is still there. The tower\u2019s bell chamber has engravings from 1851, possibly made by members of Lindhagen\u2019s<\/em> research group. The Kokkom\u00e4ki station point, filled with lead, was found to be in its original condition in an inventory conducted at the start of the 1900s. Later, more land was brought to the location, but the station point is marked with a metal pole.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ admin_label=”alatornio-church-indoors” _builder_version=”4.8.2″ _module_preset=”default” background_color=”RGBA(0,0,0,0)” width=”100%” custom_padding=”|8px||8px|false|false” border_color_all=”rgba(204,204,204,0.75)”][et_pb_column type=”1_2″ _builder_version=”4.8.2″ _module_preset=”default”][et_pb_image src=”https:\/\/blogi.eoppimispalvelut.fi\/struvenorth\/files\/2021\/08\/Kopio-tiedostosta-Alatornion_kirkko-7862.jpg” title_text=”Alatornion kirkon tornin vuosilukuja” show_bottom_space=”off” align=”center” _builder_version=”4.8.2″ _module_preset=”default” width=”100%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”|8px|8px|8px|false|false”][\/et_pb_image][et_pb_text _builder_version=”4.8.2″ _module_preset=”default” text_font=”Raleway|600|||||||” background_color=”#d1e5ec” width=”95%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false” custom_margin__hover_enabled=”on|desktop”]<\/p>\n The structures of the church and its bell chamber are unique.

This expedition was led by a Swedish scientist: D.G. Lindhagen<\/em> who worked for the Pulkovo Astronomical Observatory. In addition to the church building itself, the surrounding area was well suited to be used as an astronomical research station due to it being a central location and still not being too densely populated. The scientists wanted to be able to work in peace. Some very valuable research equipment was stored at the research station, which meant it had to be under guard at all times when the scientists were away.<\/p>\n The research station was built on an open sandy hill, 279 metres to approximately southeast from the church. On the east-side of the station was a flat area with an excellent view to the other nearby station points. The triangulation chain was aligned on the surface of the Earth with the astronomical measurements taken at the research station. The station was connected to the Alatornio church, the church of Tornio and the Kokkom\u00e4ki hill station point with a small, 170-metre long baseline and triangulation. This baseline was measured by using a pole that was exactly 22 feet in length and placed on top of three-legged stands.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ use_custom_gutter=”on” make_equal=”on” admin_label=”astronomy-research” _builder_version=”4.8.2″ _module_preset=”default” background_color=”RGBA(0,0,0,0)” width=”100%” custom_margin=”0px|0px|0px|0px|false|false” custom_padding=”|8px||8px|false|false” border_color_all=”rgba(204,204,204,0.75)”][et_pb_column type=”3_5″ _builder_version=”4.8.2″ _module_preset=”default”][et_pb_image src=”https:\/\/blogi.eoppimispalvelut.fi\/struvenorth\/files\/2021\/08\/kuussaari.png” title_text=”Kuussaari house in Raumo” show_bottom_space=”off” align=”center” _builder_version=”4.8.2″ _module_preset=”default” width=”100%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false”][\/et_pb_image][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.8.2″ _module_preset=”default”][et_pb_divider color=”#E28103″ divider_weight=”5px” _builder_version=”4.8.2″ _module_preset=”default” width=”29%” custom_margin=”4vh|||-2vw|false|false” animation_style=”slide” animation_direction=”right” animation_duration=”1150ms” animation_delay=”200ms”][\/et_pb_divider][et_pb_text _builder_version=”4.8.2″ _module_preset=”default” text_font=”Raleway|600|||||||” background_color=”#d1e5ec” width=”95%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false” custom_margin__hover_enabled=”on|desktop”]<\/p>\n At the time of the measurements, astronomy was popular outside of universities and science academies as well.

After the chains were connected, one of the triangles of the chain was formed by Kivalo, Ajos and the Alatornio church. Naturally, as the massive project progressed, some challenges were faced. One of these challenges was the fact that a proper line of sight could not be established to Kokkom\u00e4ki from Kaakamavaara.<\/p>\n Before Kaakamavaara, Lindhagen<\/em> met with the leader of the Swedish team, Selander<\/em>, in the Frankkila house in Kukkola. From there, the men continued to Ylitornio together to take baseline measurements. The previous year, Lindhagen<\/em> had worked with a team of Norwegians measuring the baseline in Alta. The baselines were measured in the field with utmost care. The baselines were converted into sides of large triangles with triangulation, which ensured the network of triangles was in the proper scale.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ use_custom_gutter=”on” make_equal=”on” admin_label=”trips-to” _builder_version=”4.8.2″ _module_preset=”default” background_color=”RGBA(0,0,0,0)” width=”100%” custom_padding=”|8px||8px|false|false” border_color_all=”rgba(204,204,204,0.75)”][et_pb_column type=”3_5″ _builder_version=”4.8.2″ _module_preset=”default”][et_pb_image src=”https:\/\/blogi.eoppimispalvelut.fi\/struvenorth\/files\/2021\/08\/Kaakamavaara.jpg” title_text=”Kaakamavaara” show_bottom_space=”off” align=”center” _builder_version=”4.8.2″ _module_preset=”default” width=”100%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false”][\/et_pb_image][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.8.2″ _module_preset=”default”][et_pb_divider color=”#E28103″ divider_weight=”5px” _builder_version=”4.8.2″ _module_preset=”default” width=”29%” custom_margin=”4vh|||-2vw|false|false” animation_style=”slide” animation_direction=”right” animation_duration=”1150ms” animation_delay=”200ms”][\/et_pb_divider][et_pb_text _builder_version=”4.8.2″ _module_preset=”default” text_font=”Raleway|600|||||||” background_color=”#d1e5ec” width=”95%” module_alignment=”center” custom_margin=”8px|8px|8px|8px|false|false” custom_padding=”8px|8px|8px|8px|false|false” custom_margin__hover_enabled=”on|desktop”]<\/p>\n Kaakamavaara is part of scientific history.
