On the territory of the Holy Trinity Monastery stands the majestic cathedral in the name of Saint Andrew the First-Called. The initiative of its construction came from the church officials: Archbishop of Astana and Almaty Alexy (Kutepov) - now Metropolitan of Tula and Yefremov, with the former vicar of the Ust-Kamenogorsk Holy Trinity Monastery abbot Platon (Divenko) appealed to the former akim of East Kazakhstan region Vitaly Leonidovich Mette (died in 2003) with a petition to allocate a plot of land for the construction of a new cathedral. Akim supported the idea, though the allocation of funds from the budget was out of the question at that time, therefore, it was initially assumed that the cathedral would be built only on donations from citizens. The new cathedral was decided to be built next to the Holy Trinity Monastery.
The construction of the cathedral began in 2001. To a large extent, it became a priority because the heads of the city and the region of that time were actively and directly involved in it – Akim of the East Kazakhstan region Vitaly Leonidovich Mette and Akim of Ust-Kamenogorsk Vera Nikolaevna Sukhorukova.
The local press monitored the ongoing processes, periodically informing citizens about the progress of construction, about who is carrying it out and by what means, attaching at first photographs of drawings and a layout of the future cathedral, and later pictures reflecting the following achievements in this direction.
The architectural appearance of the future cathedral was created by a group led by the chief architect of the project, Yuri Mikhailovich Trashkov.
St. Andrew's Cathedral was built in the finest traditions of Russian Orthodox architecture: five-domed, with a high steepled bell tower above the entrance (the same "under the bells" type of church as the original appearance of the Holy Trinity Monastery). The golden color of its domes, molded by Russian craftsmen, is traditional as well.
