Dengan penuh gairah Gereja Katedral Jakarta menyambut kunjungan Apostolik Paus Fransiskus Gereja Katedral Jakarta bulan September 2024. ALTA Integra membantu Gereja Katedral memperindah kualitas pencahayaan interior di dalam Gereja.

In preparation for the inauguration of “Terowongan Silaturahmi”, ALTA Integra has redesigned new facade lighting for this beautiful Neo-Gothic Church. “Terowongan Silaturahmi” underpass will connect Jakarta Cathedral Church and Istiqlal Grand Mosque Jakarta. This underpass will be the symbol of friendship between two big religions in the world.

Before there is no electricity and light technology, Bell is used as a communication tool from church to public. They created many bell codes to communicate different occasions, for example, three times bell sound means an invitation for Sunday Mass. Five times bell sound means there is a happy event inside the church.

Jakarta Cathedral Challenges - first as fast urban development makes a city noisier and busier, people hardly hear the sound of a church bell - second the church is surrounded by many buildings and tall trees. Answering those challenges we advise the Jakarta Cathedral Church to use light as a communication medium.
