There are several churches in the small town of Mijas, I visited the parish church, which is called "La Imaculada Concepción" or The Immaculate Conception. It existed before 1492. It was ordered to be built in 1541-65 on the site of the ruins of the ancient Moorish castle, and one of the castle's towers was used as a bell tower. It was not finished until 1631. It was restored in 1991-92 and then they found a series of frescos of the Apostles which date back to ca 1632.
The parish church is number 7 on the map.
This is the church located between the lookout point and the bullring. It is a typical looking Spanish white church that on a sunny day I'm sure looks very nice indeed.
As of most Spanish Catholic churches in Andalucia it was built on the site of a mosque in the 1500's. In fact, amalgamated with it remains a Mudejar tower of the old mosque.
I'm sure you can take a look inside if you wish, though I have to admit that I didn't go in.
The largest church in Mijas is the the Iglesia Parroquial de la Inmaculada Concepcion near the bullring. It is one of the two Mudejar churches. It stands on the site of an Arab castle. Building of the church started in the 16th century. Restoration of the church began in 1991, when frescoes of the Apostles dating back to 1632 were discovered.
The grounds around the church are beautiful. Mijas has created a gorgeous park with fountains, trees, and gardens, and a remarkable 180 degree view of the Mediterranean and Costa del Sol from the walkway around the park.
The main parish church is built on top of a Moorish castle and its belltower actually incorporates a watchtower from the fortress. Its construction was begun in 1541 and completed in 1631.
