The Javanese architecture appears to be more affected by culture of Hinduism and Javanism although Islam is the major religion of Javanese which brought a new civilization since 9th century in Indonesia. The architecture seems to be secularized from Islam since the previous principles in building are still followed. This paper studies how the Javanese synchronize the architecture based on the different older notion. Some significant samples from the most important mosques and houses in the pre-Islamic era in Central Java and Yogyakarta are analyzed to discover where Islamic signs might be found. The pre-Islamic civilization in Java are studied to understand the contextual background of the cultural harmonization. Building forms, elements, and their decorations are utilized to find the synchronization of the architecture. The result of the study stated that the Javanese did not significantly change the previous architecture, but somehow tend to adopt them into newer way of life. Though the architecture are mostly same, or slightly different if any, the newer functions are found to have also new consideration according the principles of the new religion both in space arrangement and the element of the buildings.
