museologist Maria Frigeri Horn, the museum organized a permanent exhibition room, a 19th-century room, a 20th-century room, a furniture room, a sacred art room, and room for temporary exhibitions, in addition to administrative spaces and others for various events. A public campaign was launched in the press to collect donations to reconstitute the dispersed archive. In early 1975, the creation of the Municipal Historical Archive was already planned, to operate in the same premises as the museum. When it reopened on March 2, 1975, the collection had about 500 pieces and Maria Horn as its first director. In June, the museum inaugurated a new section, the Aldo Locatelli Pinacoteca, initially destined to receive works by artists from Caxias do Sul, and shortly afterwards a section for films, photographs and recordings, and an audiovisual room were created. The renovated institution was well received by the community and soon showed significant visitation. In addition, the institution organized various events, supervised the activities of the Casa de Pedra Museum, as well as continuing to receive new donations. On August 5, 1976, the Historical Archive was officially created, being installed in a small wooden house in the back of the Museum, where the conditions were extremely precarious. The Archive became a department of the museum and in fact the two institutions functioned as one, with the same director. In 1982, the museum already had about 2.5 thousand pieces, about 700 in permanent exhibition, 300 in the Casa de Pedra, and the rest in storage, with an ongoing project to acquire 900 more pieces of agricultural machinery and tools. In the same year, a project was started to completely reorganize the obsolete system of cataloging and registration of the material. In 1984, in an agreement with Funarte, the museum obtained funds to remodel its facilities and expand its collection. However, the renovation was superficial, and from this time on the interest of the public power decreased significantly, investments ceased, cataloguing and acceptance of new donations was halted, many pieces went astray, and many others were loaned and never returned. As the years went by, the building began to show serious problems, damaging a large part of the collection that was already overcrowding the small and precarious depository. It would take more than a decade for the work to resume. In 1996, the Historical Archive finally moved to its own headquarters. In 1997, the museum started
