The village of Plassi is located near the centre of the town of Kalajoki, but is quite different in nature and landscape from the rest of the town of Kalajoki. The Kalajoki River, which changes its course according to the season, runs through the south side of Plassi; its summer quietness changes to a more abundant flow and when the winter ice breaks it surges powerfully and has plenty of water. To the west is the sea, the Gulf of Bothnia, so water is an especially important part of Plassi.

Attempts have been to preserve Plassi's landscape in the form that it originally formed into. In fact the area's old buildings are protected and are therefore in good condition. In other parts of the town of Kalajoki the landscape is typical Finnish countryside, but in the Plassi area one notices the building style of old, larger towns with trees and buildings built right next to each other; they located near the village's main street. Houses have been the homes of employees and owners of the Santaholma sawmill, which as since then closed down. The sawmill was the region's largest employer before closing and it shaped the area's settlement.

Today in the sawmill area, several companies from the wood industry to glass art have been established. Several other companies also operate in the Plassi area: a physical therapy service, a service house (a collective building), medical services, masseurs, automobile and transportation services, a nursery garden, accounting firms, fur farming, and traditionally there have always been fishermen in Plassi.

One of the most notable buildings in the area is the Havula bourgeois house, which was built in the beginning of the 1900s originally for the director of the Santaholma sawmill. The buildings functions now as a museum and guided tours are arranged for it. At Plassi's Markkinapaikka (marketplace) you can become familiar with the Kalajoki River tradition of fishing, seal hunting and river lamprey catching in the Kalastusmuseo (Fishing Museum), which was founded in 1982.

The Plassi area is home to the Jokisuu school, where children are taught for the first four years. The school started operations in 1927 and has 3 teachers a little more than 50 students.

Every other weekend in October the village of Plassi arranges large markets. This centuries-old tradition has not yet lost its attraction and for two days thousands of people gather in the Markkinapaikka to do business, socialise and have fun.

The Plassi area residents established their own village association in March 2001. Originally the village association was founded to secure the operations of the Jokisuu school, which has been at risk (of being closed). The goals of the village association is to gather ideas from residents for developing the area. On goal which has already been achieved was to make a village house from the former office building of Santaholma; it serves as a summer coffee shop.

The village house also has two permanent exhibitions. The first one was opened in summer of 2002 and displays the life and work of Unto Jutila, a composer-accordion player from the Kalajoki area. The other exhibition depicts the studio of photographer Erkki Mäkelä and even contains original photography equipment and enlarged photographs from 1928-1968. The village association has also hired a person to store Erkki Mäkelä's photographs, of which there are over 20,000, into digital form. The exhibition is open in the summer during the office (business) hours of the village house and at other times by arrangement.

The Plassi village association arranges several different events in the area. The most notable of them is Kesäjuhla (Summer Festival), which is arranged annually in the middle of the most beautiful part of summer. The them of the festival changes every year and in 2003 the theme was seal hunting. The festival also includes traditional fish dishes and pleasant togetherness. The festivals have been popular with audiences and visitors from afar have attended. Other festivals include the summertime common singing night called Kalajoki-valssi, which has proved to be a popular and fun festival. Easter is traditionally celebrated in Plassi with an Easter bonfire, which is built together by the members of the village association. Of course the festival also has a lot of other programmes and cosy togetherness.

Everyone is welcome to the activities of the village association and doing things together has turned out to be a wonderful way to create a sense of community among residents!
