In the studies conducted in recent years, examples showing that mosques with painted decoration and having quite plain architecture, which had a wide area of usage among public in Denizli and nearby cities, particularly in rural regions, continue to nowadays after the Republic period, have been encountered. One of these examples where the ornamentation comes into prominence instead of the architecture is Denizli Çameli Güzelyurt Tahtalı Mosque. Construction date of Tahtalı Mosque in Güzelyurt quarter of Çameli district of Denizli is 1956 and its ornamentation date is 1961. Besides the dates recorded within the ornamentation panels, placing name and hometown of the craftsman and miniaturist is a quite different implementation. In addition, it is also highly remarkable that these information are written on very apparent places, big in size and in Turkish characters, indeed, this is an implementation not encountered in mosques of Ottoman period. Güzelyurt Tahtalı Mosque is highly similar to late period mosques with painted decoration in terms of its sizes, materials, inner and outer roofing system and mostly for its ornamentations. The mosque, being different from the mosques with painted decoration built in Ottoman period, is a structure with a rectangle in depth plan without naves sitting on wooden columns. Painted decorations are encountered on the south front of last communion place and sanctuary of the mosque. The ornaments of Güzelyurt Tahtalı Mosque diverged from each other via the writ strip on its east and west walls, the writ strip did not continue on south and north walls of the mosque. While sometimes ornaments were framed with panels, they were placed in a free style sometimes. The ornaments of low and high levels on north walls diverge from each other with women’s gathering-place. They were organized in three levels on the south wall. Mihrab of the mosque we examine was ornamented in a quite attentive way as similar with the mosques of the Ottoman period with painted decoration. Within the painted decorations which were made with madder, far from perspective and in a miniature style brushing technique was used, however, printing technique was also used in the least on these ornaments. In conclusion, although Güzelyurt Tahtalı Mosque differs from the mosques we encounter in Ottoman Empire’s last periods, especially in rural regions in and around Denizli with its plan, it is a continuation of the tradition of mosques with painted decoration started in the second half of 18th century and kept ongoing in 19th century. The mosque, despite of the difference on its plan type, shows a high similarity with the late period mosques in respect to its small size structure, vertical rectangle space it covers, straight wooden covered ceiling, inclined roof covered with tiles and material. In addition to this, with its two dimensional painted decorations made with madder, representing a certain period, consisting of plantal, geometric, writ, architectural depictions and symbolic motifs it is very important to show that mosque ornamentation tradition of Ottoman late period was continued by public after the Republic period as well. [TR: Batı sanatının etkilerinin Osmanlı sanatında en belirginleştiği alan olan süsleme, 19. yüzyılda eski geleneklerle yeninin bir kaynaşmasını sunmaktadır. En küçük yerleşim birimlerine kadar yayılan bu süsleme Cumhuriyet Dönemi sonrasında da aynı geleneğin devamı şeklinde karşımıza çıkmaktadır. Denizli Çameli İlçesi Güzelyurt Mahallesi Tahtalı Camii bu geleneği, plan olarak olmasa da mimari ve süsleme açısından günümüzde de sürdüren örneklerden biridir. 1956 yılında inşa edilmiş ve 1961 yılında süslemeleri yapılmış Güzelyurt Tahtalı Camii derinlemesine dikdörtgen planlı, beden duvarları üzerine oturan düz ahşap tavanlı camilerdendir. Boyutları, malzemesi, örtü sistemi bakımından geç dönem Osmanlı camileriyle büyük bir benzerlik göstermektedir. Caminin son cemaat yeri ve harim mekânında yer alan kalemişi süslemeleri perspektiften uzak, minyatür tarzındadır. Kök boyalarla yapılan süslemeler fırça ve baskı tekniğinde parlak ve canlı renklere sahiptir. Süslemeler, Osmanlı Dönemi’nde yapılan kalemişi süslemeli camilerde karşılaştığımız, bitkisel ve geometrik motifler, yazı, mimari ve sembolik tasvirlerden oluşmaktadır. Güzelyurt Tahtalı Camii, 18. yüzyıldan başlayarak 19. yüzyılda da devam eden belli bir süsleme repertuvarına sahip kalemişi süslemeli cami geleneğinin 20. yüzyılın ikinci yarısında da ufak farklarla devam ettiğini göstermesi açısından önemlidir. Bu çalışma ile günümüzde terk edilmiş kullanılmayan bir yapı durumundaki camiye dikkat çekilerek, değerinin anlaşılması amaçlanmaktadır.]
