Security for Religious Sites and Places of Worship | CloseProtectionHire

Places of worship carry a specific threat profile that is unlike most other public venues. They are open by design and by theology, their congregation assembles at predictable times, they may be identifiable from outside as belonging to a specific faith tradition that is a target for ideologically motivated attackers, and they typically operate with limited security budgets and no professional security infrastructure.

The attacks on the Christchurch mosques (2019), Pittsburgh Tree of Life synagogue (2018), and Sri Lanka Easter Sunday churches (2019) have permanently changed the baseline expectation for security planning in faith settings. The Terrorism (Protection of Premises) Act 2024 has formalised legal obligations for many venues. This guide covers the threat picture, the legal framework, the physical security standards, and the practical implementation for faith communities.

The Threat to Religious Communities

The pattern of attacks on religious venues reflects a broader pattern of ideologically motivated targeting. Analysis of far-right and jihadist attack planning consistently shows religious sites as among the preferred target categories – because of their symbolic value, their open access, and the high-density congregation that maximises the potential casualty impact.

The most severe recent incidents illustrate the range of threat actors:

Christchurch, New Zealand, March 2019: A lone far-right attacker killed 51 worshippers at two mosques in coordinated attacks, live-streaming the attack. The Royal Commission of Inquiry (December 2020) found fundamental failures in threat intelligence assessment and counter-terrorism preparation. The attacks prompted New Zealand’s Arms (Prohibited Firearms, Magazines, and Parts) Amendment Act 2019 and significantly changed international baseline expectations for mosque security.

Pittsburgh, Pennsylvania, October 2018: A lone far-right attacker killed 11 worshippers at Tree of Life synagogue. The attack was the deadliest antisemitic attack in US history. The FBI assessment found the attacker had communicated attack intent online for an extended period before the attack – a digital threat monitoring failure.

Easter Sunday, Sri Lanka, April 2019: Coordinated suicide bombings targeted three Catholic churches and three hotels in Colombo and surrounding areas, killing 269 people and injuring over 500. The IS-claimed attacks exploited open-access Easter services with maximum congregation density.

Nice Basilica, France, October 2020: A knife attack at Notre-Dame de l’Assomption Basilica in Nice killed 3 people. The attack, claimed by IS, targeted an open-access place of worship.

In the UK context, NaCTSO data consistently identifies places of worship as among the most frequently targeted location types for hate crime with a physical element. The Community Security Trust (CST) recorded 1,978 antisemitic incidents in the UK in 2023 – its highest annual total – and the Tell MAMA organisation recorded a significant increase in Islamophobic incidents following major geopolitical events.

The Legal Framework

Terrorism (Protection of Premises) Act 2024 (Martyn’s Law):

The Act creates two duty tiers for qualifying premises:

• Standard duty: Venues with a qualifying activity (including worship) with capacity of 200-799 persons. Requirements: staff Counter Terrorism awareness training (ACT Awareness), a terrorism risk assessment, and procedures for initial emergency response.

• Enhanced duty: Venues with capacity of 800 or more persons. Additional requirements: a formal Security Management Plan (SMP), a Senior Premises Manager (SPM) responsible for security, coordination with the SIA as regulator, and documented standard operating procedures for terrorism-related incidents.

The SIA is the regulator for the Enhanced duty tier. Implementation guidance for faith venues is available free through NaCTSO’s ProtectUK portal. The Act received Royal Assent in April 2025 with a 24-month implementation period.

Home Office Places of Worship Protective Security Funding Scheme:

This grant scheme, running since 2016, provides funding for mosques, synagogues, and other faith buildings for physical security improvements: CCTV, security lighting, access control, and defensive infrastructure. Applications are assessed against threat intelligence held by the relevant Counter Terrorism Policing unit. The scheme has funded security improvements at over 1,000 faith venues as of 2024. Smaller faith communities that cannot afford commercial security systems should engage with this scheme before incurring costs independently.

Physical Security Controls

CCTV: Coverage should include main congregation entrances, vehicle access areas, car parks, and approach routes where public space law permits. 30-day retention is the minimum. NaCTSO recommends that recordings be reviewed after any suspicious activity incident and that the system be tested monthly. A CCTV system that is installed but not monitored provides minimal deterrent and no operational value.

Lighting: Approach routes, car parks, and perimeter areas should be lit to a standard that enables CCTV recognition and provides a deterrent to close-approach surveillance. BS EN 12464-2:2014 (Lighting of Work Places – Outdoor) provides the relevant standard for external lighting.

Access management: Open-access worship that imposes no visitor management is the historical norm for most Christian, Muslim, and Jewish communities. The security framework for open-access services must work within this constraint. Practical measures include: designated trained greeters at entrances who observe arrivals, a protocol for challenging unrecognised visitors who present suspicious indicators, and for high-risk events (high-profile religious occasions, services with politically sensitive attendance), a bag check process.

Hostile vehicle mitigation: NaCTSO’s HVM guidance for places of worship recommends assessment of vehicle approach routes to the main entrance and installation of appropriate barriers. For heritage-protected buildings, conservation-compliant temporary barriers provide an option that does not require permanent physical modification. The most practical approach for smaller venues is a planned temporary deployment of barriers for high-attendance services (Christmas, Easter, Eid, Yom Kippur, Diwali) and routine open-access at other times.

The Security Volunteer Model

Professional security officers at routine worship services are not viable for most UK faith communities from a budget perspective. The security volunteer model – trained congregation members providing a defined security function during services – is the practical implementation for most Standard duty venues.

Training: NaCTSO’s ACT Awareness e-learning (free, available at ProtectUK) is the baseline training for security volunteers. The programme covers threat recognition, suspicious behaviour indicators, suspicious package procedures, and emergency response protocols. The full e-learning can be completed in approximately 90 minutes. For Enhanced duty venues, a more comprehensive in-person training programme is appropriate.

Role definition: Security volunteers need a defined role: which entrances they are covering, what the escalation threshold is (reporting internally vs. calling 999), the communication protocol with other volunteers and with the faith leader, and the physical protocol for an emergency (lockdown procedure, evacuation routes, congregation guidance). Volunteers who are asked to manage security without a defined role, defined protocols, and defined training will improvise under pressure – and improvisation in an emergency creates additional risk.

Coordination with police: The local Counter Terrorism Policing unit (reachable through the NaCTSO portal or the local police SNT) can provide a threat briefing for the venue and advice on specific security measures appropriate to the local threat picture. This liaison relationship should be established before an incident, not as a response to one.

P1 City Places of Worship

The security environment for places of worship in P1 cities reflects the broader threat profile of each city, amplified by the targeting dynamics specific to faith communities:

Istanbul: Turkey’s religious and political environment creates specific risks for minority faith communities. The Greek Orthodox Ecumenical Patriarchate operates in Istanbul under significant constraint. For international visitors attending religious services in Istanbul, the standard city-level executive protection awareness applies, with additional awareness of the specific political sensitivity of minority faith sites.

Mumbai and Karachi: The history of sectarian violence in South Asia creates a specific threat environment for minority faith communities in both cities. The 2006 Malegaon blasts in Maharashtra, the 2010 Lahore mosque attacks (Pakistani Taliban, 86 killed), and ongoing sectarian incident patterns all reflect a threat environment that is active and documented. Faith communities and their visitors should be aware of the current sectarian incident picture, which is updated in OSAC India and Pakistan country reports.

Lagos and Nairobi: Faith communities in Lagos and Nairobi face a combination of general criminal threat and, in Nairobi specifically, the al-Shabaab church and hotel targeting pattern that began with the Westgate Mall attack (2013) and continued through the Garissa University attack (2015) and DusitD2 complex attack (2019).
