Hi. I've spotted some cracks on the lintels. The first one is above the entrance door on the west side of the building. The second one is also on the west side of the building but on the first floor with no visible signs of spreading onto stone. https://ibb.co/8szMLjf https://ibb.co/VMy9wdq https://ibb.co/TtqFCF9 https://ibb.co/vZKVPQJ https://ibb.co/k96WVpD Is it something to worry about? What's your advice? Thanks for your time.
